Create Mimic

Channeling aberrant and transmutative energy, you transform a non-magical object of Medium or smaller size that you touch into a mimic. If the object is a container, the mimic retains these items inside of it until the spell ends. The spell ends early if the mimic is reduced to 0 hit points, upon which it reverts back to its non-magical object form.

The mimic remains motionless until a creature attacks it, or until a certain condition that you decide when casting the spell occurs, upon which the mimic becomes hostile to the creature that activated it. This condition can range from something using or opening the object, to coming within a certain distance of it. You can further refine the condition by providing more specific details to the mimic, such as only activating under certain circumstances or according to specific physical characteristics (such as a creature’s height or weight). You can also designate creatures that do not activate the mimic, such as your allies or a creature that states a specific password.

The mimic is considered friendly to you and your companions, and in combat, it rolls its own initiative and has its own turns. The mimic obeys any verbal commands you issue to it (requires no action from you). If you don’t issue any commands, it remains in object form or defends itself from hostile creatures, but otherwise takes no actions. When the mimic uses its shapechanger feature, it can only take its true, amorphous form, or the form of the original object. The DM has the mimic's statistics.
