Special Traits

  • Shapechanger. The huge mimic can use its action to polymorph into a huge objects 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 Gargantuan or smaller creature adhered to the mimic swarm is also Grappled by it (escape DC 18). 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.

Actions

  • Pseudopod. Melee Weapon Attack: +10 to hit, reach 20ft., one target. Hit: 32 (4d12+6) bludgeoning damage. If the mimic is in object form, the target is subjected to its Adhesive trait.
  • Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 32 (4d12+6) plus 26 (4d12) acid damage. If the target is a Large or smaller creature, it must succeed on a DC 18 Dexterity saving throw or be swallowed by the mimic. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the mimic, and it takes 21 (6d6) acid damage at the start of each of the mimic’s turns.
  • Fighting from Within. If the mimic takes 20 damage or more in a single turn from a creature inside of it, the mimic must succeed in a DC 21 Constitution saving throw. If it fails, it must regurgitate all swallowed creatures at the end of that turn. All regurgitated creatures fall prone in a space within 10 feet of the mimic. If the mimic dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 ft of movement, exiting prone.
