Shapechanger

The mimic can use its action to polymorph into an object its size or back into its true, amorphous form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Adhesive (Object Form Only)

The mimic adheres to anything that touches it. A creature up to one size larger than the mimic adhered to the mimic is also grappled by it (escape DC equal to your spell save DC). Ability checks made to escape this grapple have disadvantage.

False Appearance (Object Form Only)

While the mimic remains motionless, it is indistinguishable from an ordinary object.

Grappler

The mimic has advantage on attack rolls against any creature grappled by it.

Spider Climb

The mimic can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
