Special Traits

  • Shapechanger. The undead mimic can use its action to polymorph into an object 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 undead mimic adheres to anything that touches it. A Huge or smaller creature adhered to the mimic is also grappled by it (escape DC 13). 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.
  • Weeping Discharge. An undead mimic constantly leaks and oozes its foul adhesive in a 20-foot-radius area around its body. The area quickly becomes coated in the fluids and is considered difficult terrain. Undead mimics are not hampered by this secretion (their own or that of another undead mimic). The slimy coating lasts for 1 hour before becoming inert.


  • Slam. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage.
  • Soul Drain. When the undead mimic kills a creature within 5 feet of it, the undead mimic can use a bonus action to devour the soul of that creature unless the creature succeeds on a DC 15 Wisdom saving throw. On a failure, the creature’s soul is devoured, it can only be returned to life by a resurrection, true resurrection, or wish spell. Each time the mimic devours a soul it gains 1d6 temporary hit points and its Strength score increases by 2. The temporary hit points and Strength last for 1 hour.
