Get back at those identity thieves.
Identifying Mimics
Mimics have are visually different from normal chests. They have a pale, cheap look to them. The biggest difference, though, is the chain (located to the right of the chest). A normal chest’s chain will go in a circle and face away from you, while a mimic’s chain will be straight and face towards you.
If all else fails, you can attack the chest to see if it’s a mimic. While this works 100% of the time, you might not want to fight it, as there is another solution to grab its loot.
Lloyd’s Talisman
You see, mimic’s have extreme insomnia that prevents them from ever sleeping. This causes them to be very grumpy, which is why they want to kill you. When you throw a Lloyd’s talisman at a mimic, it can finally fall asleep, and it gladly thanks you by giving up its loot.
This is the easiest way to deal with a mimic, though you will not get souls and it requires having a Lloyd’s talisman on you.
