Flairs are accessory-like cosmetic items that makes your heroes looks look more legendary. They are meant to add more customization ability for the heroes aside from costume accessories and also to add some "flair" hence the name. They can only be equipped through the Hero Customization Manager which can be accessed through the cosmetic button in the player's inventory. Along with costumes, accessories and tower skins, they make up Dungeon Defenders II's cosmetic system.
The flairs system is divided into four categories :
'''Head''' (halos, crowns, masks, mustaches and eyepatches),
'''Back''' (wings, tendrils and backpacks),
'''Waist''' (auras , tails and floating objects) and
'''Feet''' (auras and other effects)
