Mask of Envy is a giveaway event item from YGGDRASIL for players who logged into YGGDRASIL from 7 am to 10 pm during the Christmas Eve and remained active in-game for at least two hours.
The mask is similar to a Barong mask from Bali. Its expression can somewhat be described as neutral.
The mask could be considered as useless for it could not be customized or installed with data crystals for additional effects. It mostly serves as a mere decorative feature for a player's avatar.
- The Mask of Envy is based on the Barong from Balinese mythology.
- It was considered a "curse item" by the players, because the developers gave it as a dark joke for the single players.
- When Gazef ask Ainz to remove the mask, the magic caster tells him that it will lead to him losing control of the Death Knight next to him, which is actually a lie.
