The rash of zombie attacks throughout the city baffled both the guard and its heroes, but your party thought they tracked its source down. True enough, at the docks they ran across an undead dockhand and followed it into a run-down warehouse. Inside though, the zombie just wasn't there, only sparse, ramshackle crates. Maybe it was hiding in one of them? When you lifted the nearest lid, your skin shriveled as moisture leached from it. Glassy eyes and rotten teeth sprouted from the wood. Roll for Initiative.

It's rare indeed when a mimic suffers the curse of undeath. Rare, but not impossible. The necrotic monstrosity which results remains a dangerous ambush predator. Sure, it loses its sticky nature but drains the bodily fluids from its victims instead. On top of that, it gains the ability to mimic undead creatures and proves just as hard to put down as any other zombie.

Shapechanger.

The mimic can use its action to polymorph into a zombie version of creature it has consumed in the last 24 hours, 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.

Dry Age (Object Form Only).

The mimic desiccates anything that touches it. A creature that touches the mimic for the first time or begins its turns grappled by the mimic must succeed on a DC 13 Constitution save or become Incapacitated until the end of its next turn. If a creature fails this save by 5 or more, it gains a level of Exhaustion as well.

False Appearance (Object Form Only).

While the mimic remains in zombie form, it is indistinguishable from an ordinary zombie. While the mimic remains in object form and is motionless, it is indistinguishable from from an ordinary object.

Grappler.

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

Undead Fortitude.

If damage reduces the mimic to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the mimic drops to 1 hit point instead.

Actions

Pseudopod.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) bludgeoning damage. If the mimic is in object form, the target is subjected to its Dry Age trait.

Bite.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) piercing damage plus 4 (1d8) necrotic damage

Reactions

Flail.

If a creature holding the mimic hits a target within 5ft with a melee attack, the mimic may make a bite attack against that target.
