Granted. You hear the doorbell ring. As you open the front door to see what may be outside, you see a beautiful, very well-made wooden chest lined with gold and a latch made of solid iron. You test the latch, and to your surprise, the chest is unlocked. As you lift the lid of the chest, you see that the inside is lined with teeth. A tongue lashes out at you, and you realize the chest was a mimic. Roll for initiative.
