Guardian Armor is one of the five treasures of the Re-Estize Kingdom.
Due to it being composed entirely of adamantite, the armor is said to prevent any instant killing attack.
Guardian Armor is a full-plated metal set tinged with a colour of reddish gold.
Guardian Armor is crafted out of adamantite, the hardest metal known to man, and enchanted with magic that would deflect lethal blows.
