Avatars are costume items that a player can equip that affect the visual appearance of the player, but has no effect on the player's stats. The categories that can be equipped with an avatar are weapon, shield, upper body, lower body, and four accessories.
To produce an avatar, the player must either visit the workshop or use the player interface to enter the Production UI. The player can then choose the avatar items they wish to produce.
Each floor boss drops two categories of items to craft an avatar: super rare, and rare drops. When the player receives enough drops of each type from killing the boss, and also has enough generic floor mob drops, they can produce the respective floor boss's avatar.
The drop rate for avatar items are extremely low, though it is possible to get multiple drops from one boss kill.
Chaos Avatars are black/darkened versions of normal boss avatars, and can be obtained through Chaos Dungeonevents. Chaos dungeon events occur every few months and allow the player to challenge the boss twice per day, once in a level 70 dungeon and once in a level 90 dungeon. These bosses are much more difficult to beat than their standard versions and typically require a party to defeat, though some high level players will be able to defeat them solo. Players have 30 minutes to defeat the boss. The drop rates for avatar items are boosted for Chaos Dungeons and the crafting requirements are much lower than standard boss Avatars.
(Currently only available on Floors 5, 11, and 12)
Floor Avatars are avatars that are created using drops from Labyrinth enemies.
The Floor 5, 11, and 12 Labyrinth mobs have an uncommon chance to drop their respective Memories of ?Previous Floor?F item, which in the 11F's case can be used in combination with Dried Cactus floor drops to craft the Hanbei and Ninja avatars.
Event Avatars are given as rewards for participating in events. They are typically given in exchange for currency at the Trader, and can typically be purchased more than once, in case the player wishes to match with Koharu.
Avatars can also be bought using Arcana Gems in the Store through Avatar Orders. These are chosen at random and often are themed. Some avatars can be sold at the Avatar Shop, which gives you a small amount of Avatar Coins to spend, allowing you to turn in duplicates or unwanted avatars and eventually purchase a specific outfit or accessory. This article covers only the Free-to-earn avatars. More info on Store Avatars and Avatar Orders can be found here.
