Mimic

A mimic is a medium-sized creature who can polymorph in any object that suits the environment. Some rare varieties can grow larger, and can thus disguise as larger objects.

Description
Mimics are nearly indistinguishable from the object they are imitating, while they remain motionless. When mimics attack their prey, they grow pseudopods and typically have mouths with many teeth that appear once they have revealed themselves.

Abilities
Mimics are immune to acid damage and to prone condition.


 * Shapechanger: Mimics can use its action to shapeshift into an object or back into its true, amorphous form. Its statistics remain the same, and any objects it is wearing or carrying aren't transformed. It reverts to its true form if it dies.
 * Adhesive (Object Form Only): Mimic adhere to anything that touches them. A Huge or smaller creature adhered to the mimic is also considered grappled, and has disadvantage on ability checks to escape the grapple. The DC to escape is 13.
 * Grappler: The mimic has advantage on attack rolls against any creature it is currently grappling.

Actions:
 * Pseudopod: Melee Weapon Attack: +5 to hit, reach 5 ft., one target. If Hits: 1d8 + 3 bludgeoning damage. If the mimic is in object form, the target is subjected to its Adhesive trait.
 * Bite: Melee Weapon Attack: +5 to hit, reach 5 ft., one target. If Hits: 1d8 + 3 piercing damage plus 1d8 acid damage.

Additionally, the mimic encountered by Bells Hells was able to spit acid and do area of effect damage as a recharging ability. This ability seems similar to that of the spitting mimic, except that it could target more than one creature at a time.

Campaign 1: Vox Machina
In their second session of the home game, before Taliesin rejoined as Percy, the party fought a mimic and a gelatinous cube.

Campaign 2: The Mighty Nein
In his extra dimensional Folding Halls, Halas placed many traps to deter curious looters. In his study, he hid mimics among the cabinets in his study. The Mighty Nein encountered and fought one of these mimics.

Campaign 3: Bells Hells
While investigating the disapparances of employees and patrons of the Dreamscape Theater, the party came to a very clean but otherwise unremarkable dead-end alley next to the theater. However, Imogen and Fresh Cut Grass, using Detect Thoughts, sensed an odd presence. As the group continued to inspect the area, the striations of the stone wall in the back of the alley split, revealing the eye, jagged teeth, and tendrils of a large spitting mimic. Though the fight was harrowing, the mimic was ultimately defeated by a critical Chromatic Orb from Dorian Storm

Trivia
A mimic disguised as a chest is featured in the Campaign 2 animated intro attacking Nott who was attempting to unlock it.
