The Affluent Mimic is an enemy in UnderMine. It masquerades as a standard Chest until it is attacked or interacted with. It attacks the player by leaping at them. It can be distinguished from a normal gold Chest from its redder sparkles or observing it shuddering when a Potion of True Sight is consumed.
When killed it drops the same contents as the chest it was mimicking.
Affluent Mimic spawn rate increases significantly if the player is afflicted with Metamfiezomaiophobia. If the player is cursed with Empty Coffers, all closed gold Chests are Affluent Mimics. They will still drop their normal chest loot.
It does not drop food if the player has Leftovers.
