This information came from the official wiki. I do however interpret it into my own words. Mimic Damage: 80 Max Life: 500 Defense: 30 Mimics are immune to Cursed Inferno and Confused debuffs. Mimics are rare enemies found anywhere in the world once enabling hardmode. They can be spawned before hardmode with a Chest statute, but will not dropped items when defeated. Mimics will "mimic" regular, gold, and shadow chests to draw the player in and then attack once close enough. They can however be detected by looking closer at the chest and where it is sitting. They spawn as enemies ( in front of background objects ) so if you see a chest in front of a heart crystal or statue they are Mimics. They can also spawn with on one block underneath them or one block in them. This is another way to detect Mimics. If you have built a long bridge underground or in the underworld Mimics spawn on top of it. If you use a hunter potion or go down a cavern that you once explored and removed all the chests you will be able to detect it faster and be safe. If you use the hunter potion it is best used when in dark caverns or going down a hellivator. Spelunker potions are for detecting real chests and can not detect Mimics! They spawn in the over world ( corruption and hallow ), underground ( corruption and hallow ), and underworld. Items dropped by Mimic Rate Dual Hook 14.29% Magic Dagger 14.29% Titan Glove 14.29% Compass 14.29% Philosopher's Stone 14.29% Cross Necklace 14.29% Star Cloak 14.29% They drop one item per death. They also drop about 10 gold per death. They are easy to kill if near lava because all you have to do is draw them near you with an obsidian skin potion or grapple onto something above the lava and they will die from lava. The Mimics are slightly taller and thinner than a normal chest, and do not have a lock (except shadow chest variation). Mimics disguised as Gold or Shadow chests will not sparkle, giving them away. If I missed anything let me know and I will put it in later. This is not a perfect guide, so please don't try to criticize me as much.
