Soiled with blood and great stains, the horseless cart sits devoid of the corpses it usually bears. The cart’s corners are reinforced with rusted iron, it’s railing crafted from the same. The wheels are in good repair, however, appearing to be recently replaced. They too have been reinforced with metal. That is how this particular mimic appears until its prey draws near. The cage transforms into fangs, its wooden tongue becomes a purple, fleshy one, and spokes sprout into mottled pseudopods.

Grim Harvest. The corpse cart mimic was alchemically gestiated by La Contessa as another clever tool in her war against the ‘natural’ undead. While it can only assume one shape, the corpse cart is a devastating battlefield controller or cavalry weapon against corporeal undead. Its unique physiology renders it immune to a variety of undead attacks, and it can chow down on ghasts, ghouls, skeletons, and zombies with easy. The same can be said for pesky adventurers or innocent bystanders, or as La Countess calls them ‘collateral damage.’

Shapechanger.

The corpse cart can use its action to polymorph into an empty corpse cart 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 (Cart Form Only).

The corpse cart adheres to anything that touches it. A Huge or smaller creature adhered to the corpse cart is also grappled by it (escape DC 14). Ability checks made to escape this grapple have disadvantage.

Death On Wheels.

If the corpse cart moves in its cart form, it drags or carries grappled creatures with it as long as they are Large or smaller.

False Appearance.

While the corpse cart remains motionless in its cart state, it is indistinguishable from an ordinary cart.

Grappler.

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

Trampling Charge.

If the corpse cart moves at least 20 ft. straight toward a target and then hits it with a bite attack on the same turn, the target takes an extra 8 (2d8) damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone. If the target is prone, the corpse cart can make a psuedopod attack against it as a bonus action.

Actions

Multiattack.

The corpse cart can make two pseudopod attacks as one action.

Pseudopod.

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) bludgeoning damage. If the creature is in its cart form, the target is subjected to its Adhesive trait.

Bite.

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage plus 4 (1d8) acid damage.
