Avador's Instant Mimic

You touch an inanimate object you can see, of dimensions no larger than 10ft by 10ft. Until the spell ends, the object is transformed into a mimic imitating the object. When the spell ends or the mimic created by this spell is reduced to 0 hitpoints it reverts back to its inanimate form in a broken state.

The mimic is firendly to you and your companions. In combat the mimic uses an initiative separate to yours. It will obey any verbal commands you give it (no action required), if no action is given it will defend itself from hostile creatures but otherwise take no actions.

The DM has the creature's statistics.
