Mimics are enemies disguised as a treasure chest, hence their name. They are patiently waiting for a gullible adventurer to come walking straight into their greedy clutches. Even though they are creatures mimicking a chest, they still have unique treasures inside; which are most likely undigested possessions from their previous victim. Mimics will not respawn after they have been slain.
They look very similar to normal chests, but there are a couple of ways to tell them apart.
All chest have a chain attached to its right side. A Mimics chain is shaped like a straight line, while the chain of a normal chest is more curved.
By looking at a Mimic with the binoculars or a bow, you can see the lid opening around every 10 seconds when it takes a breath.
If you look closely, you’ll notice that the colour of a mimic’s chest is paler than a regular chest.
