YGGDRASIL
"A DMMO-RPG where strength is not everything."
- Creators describing the game, YGGDRASIL.

YGGDRASIL (ユグドラシル Yugudorashiru) was a fictional online game in the Overlord series. It was a DMMO-RPG (Dive Massively Multiplayer Online Role Playing Game) developed in Japan.

Infamous as the game was, its degree of customization made YGGDRASIL so popular that at one point in Japan, the word "DMMO-RPG" was practically synonymous with YGGDRASIL. The DMMO-RPG's feature ignited the creative spirits of its Japanese players, and sparked what would later be known as a Stylistic Revolution.

On the other hand, the game had been active since its release in 2126 AD and until 2138 AD. In the current year, 2138, however, the game's community by then already lost the vibrancy it once had. As a result, the remaining players still playing YGGDRASIL met their final day online.

Description

YGGDRASIL is a DMMO-RPG released in 2126 by a Japanese Developer. According to the developers' website, YGGDRASIL was a game of exploration, and so many things were mysteries left unknown for players to discover on their own or in groups. It was a game where all you were told was the controls before being thrown into the deep end. In other words, the special thing about YGGDRASIL was the incredible amount of freedom given to players, compared to any other DMMO-RPGs out there.

YGGDRASIL requires an exclusive console to play, which records logs for the week. Though the game is full virtual reality, it does not provide a sense of taste or smell, and has a limited sense of touch. Due to the lack of technology when the game was developed, facial expressions and artificial intelligence are not supported. However, there were statuses like hunger and thirst which existed among players and the mounts they ride on in the game.

Furthermore, the most distinctive feature of YGGDRASIL was its flexible system to allow players to freely make choices. Players could select numerous races, jobs and various tools, allowing for customization in the game. If a player were to use separately sold creator tools, they could freely alter the appearances of weapons, armors, interior data, character visuals, and advanced settings of their in-game residence or home. The customization system was really far-reaching and broad, even allowing basic programming.

When It came to Equipment in YGGDRASIL, one could equip magic items in the following slots: head, face, body, three pieces of jewelry apart from one’s rings, underclothing, arms, hands, left and right rings, waist, legs and feet. Even a suit of full plate armor only counted as taking up the body slot. Players could only put one ring on for each hand. However by using the power of a Cash Item, players are able to put a ring on each finger. A player could tinker with the game's database by using the creator tools and form original items. One could also buy appearances within the DMMO-RPG. Through doing this, a player is able to create an unlimited variety of original items. After a certain patch was updated into the game, players were given several ways to change their equipments’ appearance without changing their gear.

Momonga using one of the emoticons to express his feelings.

However, there are player characters from different races who are unable to make facial expressions in the game. In the beginning, YGGDRASIL characters had no facial expressions. As a result, a player’s avatar could not change expressions to match their voice. At the same time, a character’s mouth would not move with their words. Later on, external appearances were fixed.

Because of this, facial expressions were impossible to design, however, it was somewhat possible for a player's expression to change by using their own words. For example, it would not be that difficult for humanoid players. However, it is impossible to do so, since writing macros to move the faces of demi-humans and heteromorphic beings was extremely difficult. Instead, players can used their bodily motions to compensate for the lack of facial expressions in YGGDRASIL. Not only that, but a player can also touch their console to select various faces from one of the emoticons, using it as a way to identify the feeling and mood they have right now.

The game had a system where players could pay a fee in order to participate in a lottery to win a rare item. This would include a type of cash gacha within the game where players had the opportunity to cash in money with the chance of winning a prize.

Cosmetic skins were only released and made available in limited quantities. If one missed out on them, it would be extremely difficult to acquire them afterwards. As such, players tended to buy up any new cosmetic item that looked halfway decent.

On the other hand, YGGDRASIL developers did not provide any information about the game world’s map, and they were also inconsiderate enough not to supply any news about the game’s dungeons and things such as ore mining, food preparation or the raising of magical beasts. In a world like this, one had to investigate and discover things on one’s own. In fact, even the items that one could and could not use could only be felt out through repeated trial and error on the player’s part. There were walkthrough sites and news sites, but those sites only hosted a compilation of publicly known information or very untrustworthy rumors. YGGDRASIL was a game of exploring the unknown. Thus, any information one uncovered would be very valuable. There was no merit in publishing this valuable information for any stranger to view free of charge.[1]

More importantly, YGGDRASIL was a game where information itself held value with a great example being the World Item. The number of people who freely shared newly discovered information with others was small and they usually had to pay a price if they wish to know about it. The same could also be said with classes such as Eclipse that possessed a secret trump card. Although a lot of information had already been collected, most of it pertained to dungeons or other locations, and it was estimated that only 30% of the nine worlds had been mapped so far. During the final years of YGGDRASIL, the chances of reliable information being made public on the web was rather high.

There are endless discoveries (special classes, items, etc) players could find and obtain through adventures, such as focusing on certain skills like instant death spells etc. with one example being the Caloric Stone, a World Item among one of the hidden items discovered in the game. Besides World Items and skills, there are also apoithakarah, scarletite or other prismatic ores that were of the highest tiers in YGGDRASIL.[2]

Game's Functions shown by Momonga before YGGDRASIL's shutdown

When it came to players, functions existed (Forced System Access, Chat, Call GM, Log Out, and so on) that they used in the game. For example using the shout command or a GM call would put the player in touch with a GM almost immediately, and shows how effective the functions were. Another example is the chat channel, where players can look up recent news, like the shutdown of YGGDRASIL. In addition, players can open a system console and connect to the developers’ website to inspect the official guild rankings.

Worlds and Dungeons

As it can be guessed from the title, YGGDRASIL mainly refers to Norse mythology, and has nine separate worlds based on it which are: Asgard, Álfheimr, Vanaheimr, Niðavellir, Midgard, Jötunheimr, Niflheim, Helheim and Múspellsheimr. While each world is a leaf of YGGDRASIL with their own particular traits, they were estimated to be two to three times the size of Tokyo. Other leaves were eaten by Navagraha the World Eater, or shed and transformed into World Items.

There were nine huge Guild Bases of level 3,000, one for each world. If a weak guild were to control it, they would immediately be embroiled in complex guild wars, and holding on to the base would be very difficult.

Each of them was ridiculously huge, and there were many places within them which were difficult to explore. For instance, there were gigantic swamps, verdant expanses of rain forest, scorching deserts and the like. Players needed special equipment to delve into the dungeons there, as have a proper strategy and the determination to their life away for the trip. This was because these hard-to-find dungeons contained monsters which dropped valuable data crystals.

In any world, be it either Niflheim, Helheim or Muspelheim — things became more dangerous the further one went from the center of the world. In addition to wandering monsters, the very terrain itself became a hazard.

Some dungeons could only be found under certain conditions. For example, the entrance to a dungeon amidst a field of flowers in the depths of a forest could only be seen under the light of the full moon. Additionally, there was also the Frozen City in Niflheim, which could only be entered during a blizzard.

The first time one ran a dungeon, there would be a bonus, or about 10% more treasure chests. Also, the first time a dungeon was cleared, the big treasure chest would offer equipment with item levels up to 10-20% higher than usual. Clearing the dungeon under certain conditions would reward a World Item such as the Throne of Kings.

Tabula Smaragdina stated that dungeons existed with an even higher difficulty than the Great Tomb of Nazarick. In particular, he seems to know that one of those unnamed dungeons needs 36-man parties (a legion) and allows two guilds to cooperate in invading them.

Dungeons ranged from different types such as a simultaneous attack dungeon like Nazarick. Many people hated simultaneous-attack dungeons, also known as “die-by yourself dungeons”. Dungeons like these required several parties working in unison along different routes to complete and were typically designed so that everyone would meet up at the boss room, where they would face the raid boss together.

Level

In YGGDRASIL, the maximum level a player can reach is 100. The game YGGDRASIL has two types of levels, Racial and Class levels. Monsters are different, however, since they not only have Racial and Class levels, but Monster Levels too. This is added to Class Levels if they have any.

Additionally, when a player died, two things occurred. The first was the loss of experience points and a consequent loss of levels, enough to set you back 5 levels, though that depended on the way they were resurrected. In YGGDRASIL, this wasn't that big of a drawback, since experience points could be regained rather easily unlike in other games. Characters below level 5 would disappear immediately upon dying, however, the death of a player character with a level lower than 5 will just revert them back to level 1. Secondly, one would drop a randomly equipped item. In other words, when a player character dies, they lose 5 levels and drop a random piece of equipment they had equipped.

Players could lose one or more pieces of equipment if a dungeon expedition happened to be very difficult. Because of that, players sometimes geared themselves up with second-rate items, the kind they would not mind losing. However, players could not clear the dungeon in one go with second-rate stuff, so they had to use their best equipment. The developers designed the game so that the most valuable gear would be dropped first, which meant that the chances of an important item that was key to the player’s strategy being dropped would be greatly increased. Nevertheless, this penalty can reduce a bit of experience loss by using certain revival skills or cash items.

As monsters went up in level, they gained all sorts of special abilities. At this level, they could greatly decrease any damage done to them. As a player would level up in a party, the amount of experience points gained was reduced in accordance to the level difference between both parties, to a minimum of one point. If a player's level goes down, the skills they've acquired at that level will also vanish and can no longer be used.

However, players who wanted to respect their characters often favored using death as a means to lower one’s levels, so they can gain other racial or job classes in place of their old ones. Though the loss of even a single level is considered to be a harsh punishment in a game where each level required a lot of experience points, losing levels was a very lax prospect in YGGDRASIL. In fact, the company behind YGGDRASIL wanted its players to explore previously undiscovered regions and find new things, rather than hunkering down in familiar territory just because they were afraid of losing levels.

Resurrection

When a player uses a revival skill, he or she can choose the location they desire. Afterwards, there were four optional methods of resurrection to choose from in exchange for experience points. The first type was on-site resurrection. The second type was resurrection at the entrance of a dungeon. The third type was resurrecting at a nearby safe town. Finally, the fourth type was resurrection at a specified location, such as a guild base where the player is situated in and is a member of.[3]

However, if your character or NPC were to get affected by a World Item like Longinus, it will be impossible to revive the individual without help from the resurrection power of other World Items. There are even items such as one of Ainz's rings that allow him to lower the cost of resurrection.[4] For Shalltear, she has a resurrection item which allows her to instantly revive herself upon dying.[5]

In YGGDRASIL, using spells like [Resurrection] or [Raise Dead] would mitigate a player's level loss if they were to die. On the other hand, NPCs belonging to players or guilds can revive instantly by paying the right amount of gold fee depending on their amount of levels in particular. Their revival doesn't come with the loss of levels, but gold coins instead. As long as the guild paid the requisite fees to resurrect them, they would be revived back to life without any ill effects.

Gold Coin Currency

The gold obtained in YGGDRASIL wasn't just used to buy items, it was also used for many other things in the game. One of those things included covering the administration fees for managing a Guild’s base-defense systems. In addition, it also provided the costs for automatically summoning servants of level 30 or higher, as well as a required medium to launch certain spells. Gold was used to pay the manufacturing costs of items, and even the revival of dead NPCs too, in which the price for doing so can vary depending on their level.[6]

Through using separately sold creator-tools, players could even customize the appearance of YGGDRASIL's gold and experience points in place of its original setting. For example, say a player has killed a dragon. Gold, data crystals and experience points will still continue to drop by these dragons as per normal DMMO-RPGs, but by modding the game, it only makes the visuals of them being dropped by monsters different. While the dropping of gold and experience points does not change, crystals containing data are the ones that dropped instead.

Defeated monsters dropped money very easily. This was because there were many crafting classes in the game. Most of them made scrolls, wands, and staves, which were frequently used by magic casters, in which they could use as well. If less money dropped, magic item production would be very difficult, and magic-using classes would have to think twice about going into intense combat on adventures. This went against the design philosophy of having players explore the world. Therefore, the game was actually much more generous than its contemporaries with dropped money.

Races

There are more than 700 races, including racial classes that need certain levels of low rank racial class to learn. Races of YGGDRASIL can be roughly categorized into three taxa. In the game, demihuman and heteromorphic races unlocked racial skills when they reached certain levels. Some items can change races permanently. In the game, humans and demi-humans, who had limited lifespan, would grow and age normally. In contrast to them, heteromorphic races with unlimited lifespan would stop growing after a certain stage.

  • Humanoid Races include humans, elves, dwarves, etc. Humanoid races are weakest in basic status and cannot have a racial level. Instead, they can learn more classes which provide high stats or powerful skills more easily, giving them higher potential. Having familiar appearances and advantages, human races were the most popular in YGGDRASIL.
  • Demi-Human Races include orcs, ogres, lizardmen, etc. Demi-Human races can have more basic statuses and have a racial level. Demi-Human races are similar to the average between Human races and Heteromorphic races. While the Demi-Human races weren't visually appealing they can still perform better than Humanoid races.
  • Heteromorphic Races include slimes, vampires, devils, etc. Heteromorphic races own the most powerful basic statuses, which can be strengthened even more by increasing their racial level. High-ranking races also provide special abilities similar to that of a monster's. Beside providing racial level and special abilities, the Heteromorphic races are able to also gain more ability points than the Humanoid or Demi-Human races. However, they were penalized in other ways as the racial level comes at a cost where it limits the amount of job levels players could learn. Thus, Heteromorphic races were very unpopular just for that reason. PKing a Heteromorphic player doesn't give any penalty to the player that did it.

Classes

Main article: List of Job Classes

The class system is considered to be the key element of character customization. Counting the advanced classes as well as the based classes, there were more than 2,000 classes in YGGDRASIL that players could choose from.

Although 15 is the highest level reachable in a single class, there were some high-rank classes that seemed to have lower level limits. Therefor, it is actually possible for a player to own at least 7 or more classes by the time they hit the overall level cap of 100. If one ignores efficiency, it is also possible to get a hundred level 1 classes. There are also some 'optimized' class builds discovered by players. In other words, it was a system where it was impossible to have completely identical characters unless you intentionally made them alike.

Additionally, experimenting with different classes was only possible by dying and losing levels. Even if it was easier to gain levels in this game, it was still a time-consuming process for most players. In fact, some powerful classes were unlocked by PKing heteromorphs, and made it beneficial among players. In normal games, most people would spread the news of a newly-discovered class on walkthrough sites to share with others. However, games like YGGDRASIL put a very high premium on information.

Depending on the skills and abilities they possessed, players can pick up different pieces of additional information upon exploring a new area. For example, class like the alchemists and herbalists, with their herbalogical skills, would be able to learn about the various herbs that they could harvest in the area.

Whereas if there was someone who is level 90 with a rogue class job, or a character over level 80 with full specialization as a rogue, it was near impossible to open a locked box. In a way, a high level thief would be able to steal items from the box. Just because a rogue could, It did not mean said rogue could just immobilize their opponents and rob them dry. The limit would have been one or two items per player.

There were also some classes in particular, which had the penalty of not being able to summon monsters whose karma values were far too different from their own. However, the fact that Ainz did not have such classes was why he is still somehow capable of summoning angels through using a super-tier spell. Incidentally, the monsters summoned by those classes can only become stronger the closer the monsters’ karma values were to their masters.

The warrior classes were limited by one's real-world reflexes, that restriction only came into play during duels between top-class warriors. For that reason, warriors need to have a good body in real life to perform well in-game. It was not a deciding factor during normal play. According to Touch Me, when in battle, one could instantly sense an opponent’s intentions, thus evading his or her attacks.

Not only that, there were classes with actual stories behind them. For instance, Cursed Knights had the backstory of being corrupted cleric-knights who had been cursed for unknown reasons that aren't clear yet. Particularly, very strong classes like Cursed Knights are bound to have weak points and penalties as their drawbacks to make the game more balanced.

Skill Points

Skill Points increase with racial and class levels. The growth rate goes in this order: Heteromorphs> Demi-humans> Humans. For a random skill point, a human (Human Race) would be one, a goblin (Demi-human) would be two, and a Skeleton Mage (Heteromorph) would be three. This is the case of comparing between their best stats, and it should be fine to think of as the general case.

Within the first level, a human has no racial level and would go to their class. A fighter’s skill point would raise by two. For the first level of human, their skill point would be three (2+1: Class Level and Race), a goblin four (2+2: Racial Level and Race), a Skeleton Mage six (3+3: Racial Level and Race). In relation to the raising of racial skill points, a Human and Skeleton Mage would have a ratio of 1:3. At Level 100 it would be 100 to 300 (This is a rough estimate). Since it works this way, heteromorphs are considered strong.

Unfortunately, after taking a new racial class, the rate of skill point increase would favor the most invested, and so the skill points would also increase. In addition to that, heteromorphs have penalties. They cannot have certain classes, cannot enter certain cities, are fine to PK, have penalties depending on race, and cannot equip certain equipment. Even if they take only one level, the penalty activates. However, the final Racial Class of the heteromorphs have very high skill points. Due to their high skill points, strong skills will become immensely stronger.

Meanwhile, jobs that have difficult requirements would have a higher rate of skill point increase. For example, in some cases, humans would only be able to have that class. Rather than increasing Racial Class, characters that take various classes would be stronger. This is to consider skills as better than skill points. There is a theory that if one wants to make a strong character, they should not raise their Racial level. That is why humans are popular in YGGDRASIL and not heteromorphs.[7]

Guild

A guild could conquer a dungeon and use the place as their headquarters upon being granted ownership rights. However, guilds could only own one dungeon at a time. If a guild wanted to claim another dungeon, they would need to relinquish ownership their current one.

There were just under 800 guilds created within the game,with a guild's ranking system consisting among them all. In addition, discovering a dungeon could affect the world ranking of a guild. YGGDRASIL has a clan system which differs from a guild system, although the latter has both. Guilds are also granted NPCs, so they can set them up to protect their base.

There are three categories to these NPCs being:

  • Spawned NPCs pop-up automatically from the dungeons. The monsters which automatically spawned under level 30 had maintenance costs depending on their type. It was 0 for undead, but for living creatures, particularly large creatures, they had maintenance costs which increased proportionally to the size of their bodies. In YGGDRASIL, players could place pop monsters within dungeons by paying the appropriate in-game or real-world currency. However, they would not come back to life after being destroyed, so they were more of a luxury to players.
  • Mercenary NPCs can be summoned by spending guild finances. In addition, the mercenary system that summoned creatures in exchange for YGGDRASIL currency did not allow for the summoning of Death Knights. One good thing about them was that it could allow a solo player to form a group, however, their AI was not very good, and their combat ability was lower than even a poorly put-together character of the same level. Upon grouping with such NPCs, people who aren't good enough were hindered when running difficult dungeons.
  • Custom NPCs can be customized freely, with their power level depending of the level of the guild stronghold. The lowest-ranked guild headquarters provides 700 level to be shared between NPCs. This can be increased by upgrading to an higher-ranking dungeon, using cash, etc. Customization tools included not only levels, equipment, and appearance, but AI too. Thus custom NPCs can be made and used as powerful guardians. Of course, a guild is totally free to customize its NPCs just for decoration purposes.

Financially, a guild base which only popped large living creatures would rack up a ruinous maintenance bill. If a guild base’s innate income was not sufficient to cover those costs, the guild members would have to earn that money themselves. In addition, trap activation and monster summoning were expensive. Being attacked by an enemy guild could incur incalculable expenses for the defenders, and might even force them into bankruptcy.

Magic

More than 6,000 different spells exist in YGGDRASIL. While magic in YGGDRASIL had a ridiculously large number of spells, they could not be changed nor made by the creator tools, and it was impossible to use all of them. A level 100 spell caster usually knows around 300 of them (3 x caster level in the Web Novel). Even basic functions such as messages needs spells to use, so most of the spell casters have trouble managing all the spells they desire to have.

There are cash items that could actually increase that number by another 100, making it a grand total of 400 spells within their control. Whereas bonus abilities like "Dark Wisdom" could be inherited from a race such as Overlord, and grant the player of that kind up to 718 spells, which is largely twice the amount a player could learn at a max of 300.

Firstly, in order to learn magic, you must first fulfill the necessary prerequisites. For starters, there are selected classes a player must choose, special events they must go to, they must use certain items, and so on, in order to learn magic. If successful, they are able to use the selected magic type of their choice. And for that purpose, there were players who devoted 1/3 of their total magic to the prerequisites. Some players also tended to give up learning as they could not clear the prerequisites.

For those who are attempting to become specialists, there was a problem about what to choose. It was extremely common that the magic that they wanted to learn was not within their field of expertise. It was not rare among players to die repeatedly and recreate one’s classes every once in a while. Also, there was the tricky problem of handling the stats that come along with it.

If the player's magic power or level was high enough, they could potentially deal more damage with a spell, or maybe their range would increase more than other lower level players using the same kind. In this case, let's assume that there was a player who specializes in faith-type classes, and is a user of the "Fireball" spell. Based on the damage and distance capability, their spell would not be as strong as other players who use it with classes which focused on magic power.

To start off, magic is divided into eleven tiers: From Tier 1 to 10 and exceeding passed it is Super-Tier Magic. Super-Tier Magic has miraculous power that is compared to a 10th tier spell, but suffers from huge casting and cool down time, preventing the frequent use of it. Casting super-tier magic decreases the magic caster's defense, while receiving a certain amount of damage cancels the casting.

As consoles are mandatory for the game, they're required to access the players' spells within their arsenal. The hotkeys on the console, ranging through a selection of the numbers 1 to 10 represents the ranking of tier spells a player can choose from, and used in varying numbers. Players could arrange these spells via hotkeys. Momonga memorized them. Each spell has an icon, which players could tap on to begin casting it. The player can tap other hotkeys if one was planning to apply some sort of metamagic enhancements to their spells.

When the player starts casting their spell, an arcane eye or a magic sensor would have appeared in front of the caster. Afterwards, the player could manipulate the sensor by sending their spell towards the desired area of their choosing to initiate its power or effect once they're ready to finish casting it. The player's right hand held the control stick for the sensor’s movements, whilst their left hand directs the sensor’s field of view. Other than that, there are icons representing buffs and debuffs that could appear in the player's field of vision, so one could see whether or not they were under the effect of an ability.

A player could hotkey up to about 480 spells in total. The ability to skillfully navigate these menus meant fully understanding and memorizing the effects and proper application of each spell. It was considered to be one of the biggest factors in one’s ability as a Magic Caster. Just as warriors were affected by their real-life reflexes, magic-using classes relied heavily on their memory. A magic caster’s strength is measured by the number of spells they know.

MP

Once a magic caster is out of MP, they are no longer able to cast spells. No MP recovery potions existed, and the magic caster must wait to completely recover their MP for 6 hours. Incidentally, the base MP was their level times 10.

Ability Types

There were two kinds of special abilities in YGGDRASIL. One had a cooldown period after use. The other had a limited period of uses within a time frame. There were also combinations of the two. In general, the more powerful the ability, the longer the cooldown, or the fewer times it could be used in succession. For instance, Ainz’s trump card, [The Goal Of All Life Is Death] is spell that could only be used once every 100 hours (while YGGDRASIL was online).

Parties

Parties were mainly made up of six players in total, and a dungeon raid could have a maximum of 5 parties. In other words, the maximum size of dungeon raid consisted of 30 people in total when taking on bosses. Apart from exceptional cases like guild battles or fighting a World-class enemy, people who were over the limit would be subjected to friendly fire. If there were joke characters with a dream build among them, it would reduce the amount of fighting power they could bring.

They are categorized under Magical Attackers, Physical Attackers, Tanks, Healers, and Seekers and Other. The "Other" category is viewed as those with challenging classes who were able to adapt to many different circumstances in any situation such as players like Momonga.[8]

Nevertheless, the basic 6-man party configuration in Yggdrasil was one tank, two attackers, one healer, one seeker and a wildcard, who was capable of adapting to changing situations. Anyone taking on this task needed to be intimately familiar with everyone’s abilities and preferences. A team that was put together sloppily would not be able to succeed. Therefore, assigning party rosters was one of the greatest challenges of such an endeavor.

In addition, the sentries is formed as a party which would be used to stand guard at the dungeon entrance. Thus, they tend to keep a close eye out for anyone approaching the entrance. Depending on the circumstances, they were willing to go so far as to eliminate any interlopers.

In many games, one could not reorganize a party outside of a safe zone, or certain designated locations. In YGGDRASIL on the other hand, one could instead freely change one’s party anywhere and anytime. This allowed for very flexible parties, and with a good team, one could overcome any difficulty. By doing so however, the effects of party-wide magic and skills terminated once the party was disbanded. One had to take that drawback into consideration when regrouping. That trick would not work if used in a dire situation.

PVP

Otherwise known as Player vs. Player.

According to Momonga, the most crucial thing in PVP is to deceive one's enemy, such as in his battle against Shalltear Bloodfallen. For instance, pretending that one player is vulnerable to holy-elemental attacks when they're largely immune to them after swapping out their gear, while also hiding the fact that they're weak against fire-elemental attacks.

PVP is the usual tactic used by a group of human players in order to hunt down heteromorphic players. Doing so will also be label as PKing which is player killing. There exists the contents of "PKing for Dummies" in which Momonga has spoken of before. Furthermore, there is also no penalty for PKing heteromorphic species existing in the game.

According to Punitto Moe, “Squashing” was what they named their PK method that involved attacking a player group that had just began delving into a dungeon from behind. Once their opponents were forced deeper into the dungeon, they would have to deal with the dungeons’ monsters as well as the PKs attacking them from behind. This was a kind of pincer movement.

Furthermore, Momonga stated during his battle with Gazef Stronoff that having a weapon which is capable of killing someone is the absolute minimum condition for a solo PVP duel. In other scenarios, there was also a type of No-Loot PVP or the latter that he knows exists in YGGDRASIL.[9]

Some players would prepare a set of identical looking gear, equipped with completely different data crystals. In PVP matches, small tricks like that improved the players' chances of victory against their opponent. Although backup gear was typically weaker than one’s main panoply, being able to surprise a foe had effects beyond mere data values.

There is a limited cooldown period to players casting the number of spells from Super-Tier Magic. In addition, this cooldown period could not be eliminated by any skill or cash item. Thus, when PVPing, the party that casted a super-tier spell early was often considered an idiot. After all, defeat was likely the outcome any player will face when they expended their own trump card without properly understanding one’s foe. There were very few PVP battles where the victors were the first to cast super-tier spells.

Strong fighters in PVP matches have the tendency to be very popular with spectators. The voices of the supporters would slowly turn toward the challenger if they did well. In other words, if a player fought well against their opponent, more and more people would start to support that person.[10]

Items

Main article: List of Items

Items are classified accordingly to the following rank system:

  • Low → Middle → High → Top → Legacy → Relic → Legendary → Divine
  • Artifacts are not related to specific ranks, it just means they are items with fixed data. Therefore, artifacts with a low rank can also exist.

Items drop as a data crystal from monsters, and players can produce items freely in the capacity of crystals, including options to customize their appearance and name. As a result, these data crystals could be slotted into almost any sort of item (apart from certain expendable items), in order to create just about any item a player could think of. In addition, there were certain artifacts which could not be created by players and had fixed stats. For example, Horn of the Goblin General.

Clearing a dungeon often yielded a variety of items, from rare data crystals to artifacts. In order to make, for example, a data crystal into weapons and armor, it is through inserting a data crystal into an item skin. While magic items in YGGDRASIL were made by infusing an item skin with a data crystal, it was actually quite difficult to coordinate their appearance for players. After a certain update by the game's developers, players were given several ways to change their equipment's appearance without changing their gear that had stat boosts in it.

Players could design their equipment as they liked. Additionally, this included their powers as well. Player-made items in YGGDRASIL could also have their abilities be changed up by using data crystals. Yet the same way may even applied to the equipment used by NPCs like Narberal that had a quick-change crystal embedded in it and used for battle. That way, they would be able to directly swap out their gear for a set of predetermined equipment without having to waste time changing.

YGGDRASIL's equipment was classified by how much data each item possessed. Items with more data were ranked higher. However, abilities could not be stacked randomly; the capacity of an item for data was determined by the item's construction and the material. In contrast, special effects took up a smaller amount of data capacity, so it was not uncommon for them to be imbued in an item to use up the leftover capacity. For that reason, not all data crystals dropped by monsters were equal. If one wanted to make a divine-class item, one would need several data crystals which were classified as "high-rare drops".

When comparing a sword made of clear crystal and a sword comprised wholly of iron, the amount of data needed for the exterior is completely different. The amount of data is determined by the resources of the item, such as minerals. The goal was not only to destroy monsters, but also to search for resources and to explore for new discoveries. Players often called themselves adventurers when doing such things.

Theoretically, one could create the ultimate weapon by embedding damage-increasing data crystals into a big weapon with high data capacity. Yet, weapons like that were unwieldy, and would result in fewer attacks due to the difficulty of using them. Thus, the wielder's overall DPS (damage per second) would go down. It was quite common to require weapons made of special materials or with the appropriate elements to bypass monsters' abilities. The smith was also a key part of the equation. In YGGDRASIL, humanoids called Dwarves had bonuses to craftsman-type classes to craft these weapons.

In YGGDRASIL, trading in magic items was usually done in the form of data crystals. However, there were people who sold second-hand items in order to make even stronger ones. It was at this point that a problem arose — the names of magic items made by other people might include forbidden language, or it might insult someone. Sometimes, the GMs would ask the players in question to rename the items. Most players named their equipment in reference to legends and mythologies, in order to make them an easier profit to sell. There were also cash items which could rename them as it wasn't expensive.

There are also World Items, whose power overrides the limit of other items. Many of them can ignore or even change the game system of YGGDRASIL.

Monsters

Main article: List of Monsters

There were very few monsters in YGGDRASIL with attacks that were vastly different from what their appearance suggested. However, there were many enemies whose moves could not be predicted and are a special case. Most monsters were generated by the same rules used for generating player characters. Even the magic they used was the same. The values derived from their basic stats such as health were also of a similar nature.

There were spellcasting monsters in YGGDRASIL. While the numbers of spells they could use varied greatly according to their level and species, they could use about eight kinds of magic.

When monsters attacked, they would target the one they wanted to hit the most. This could be expressed as a numeric value, called "hate." Causing more damage, healing HP, buffing, debuffing or using taunting-type skills would increase hate. When a player was hit by a monster, it would resolve the matter and that monster's "hate" of the player would decrease. Because hate values fluctuated often during a battle, tanks had to pay close attention to monster's "hate" values, or the backliners would take a hit.

Dungeons have bosses with different abilities, appearances, and boss rooms. Boss battles typically took place in a separate map, and there were some boss battles which allowed players to retreat from the fight. Regardless, altering the terrain was a common tactic performed by raid bosses.

Among the most powerful monsters in YGGDRASIL are called a "World Enemy". Even Legions (6 parties with 6 players each) can have a hard time fighting against them. In one example, a guild was attacked by a World Enemy — an immensely powerful, hidden boss monster — and nearly destroyed them as a result. Attacks from a World Enemy are capable of bypassing the target's racial resistance. Some of them are related to World Items. To the developers, the incredibly powerful last boss of the main campaign story-line known as the "World Eater" was the signature World Enemy.

There were at least about 32 level-breaking bosses in YGGDRASIL and some of them are listed below:

  • Devourer of the Nine Worlds
  • Eight Dragons
  • Lords of the Seven Deadly Sins
  • Ten Great Angels of the Tree of Life
  • God of the 6th Day
  • Five Rainbow Buddhas
  • World Eater

In YGGDRASIL, there were two major patterns of raid bosses. The main problem with designing boss encounters was that the players had the same skills and spells that monsters did, but during raid boss encounters, there would be 30 players facing a single monster. Even if with enhanced stats, one monster would still be obliterated by the sheer weight of a parties numbers, which meant that there was no challenge at all.

As such, two main types of boss encounters appeared to address the issue. The first was the boss would come with minions, or the boss arena would constantly spawn monsters. In this approach, the boss wasn't usually that strong. In some cases, it would only have several times the health of a player character.

The other method was to send out a single boss, generated with different data from the player characters. This sort of boss typically had abilities which would give parties a lot of trouble when encountering them for the first time, and it could use those abilities continuously. Judging by the look of the boss, it was highly likely that it fell into the latter category.

YGGDRASIL and the New World

Main article: New World

Once every 100 years, players of YGGDRASIL are teleported without reason into the New World. It seems that the first teleportation had occurred 600 years ago. With the knowledge and exceptional power of YGGDRASIL, the players usually shake the very foundations of that world, making them legendary godlike figures to some of the native inhabitants' view.

Ainz Ooal Gown is currently the only known player to have been teleported to the New World when he was expecting to be forcefully logged-out of the game during the shutdown of YGGDRASIL. From this moment forward, Ainz later decided to make an everlasting name for himself in the New World.

Changes

After arriving in the New World, players like Ainz felt that some of the game's functions from YGGDRASIL had been removed and they could access them anymore. For instance, Ainz was no longer able to summon a command console. The game's functions, such as forced connections, the chat function, a GM call, and the forced logout are no longer accessible in this world.

Other changes include the modification of various spells of different tier in terms of area and effect magnitude. For example, a player using the [Message] spell now has the power of constantly reaching out, as though looking for something to connect to. Yet, at the same time, players and their summoned monster shared a special connection similar to that of a master and servant relationship.

The actual process of casting a spell is faster than it was in YGGDRASIL. Unlike in YGGDRASIL where the player must tap on an icon to cast a spell, one must concentrate mentally for an icon to appear out of thin air to start the casting. The player would feel that Tier Magic was part of them. To Momonga, this was satisfaction a player like himself could never have experienced in YGGDRASIL until now.[11]
