Coffin Mimic




As ostentatious as it is deadly, the coffin mimic fits right in with the rest of a vampire crypt’s decor. This is the point, of course. The monstrosity exudes a coppery perfume that most undead find particularly irresistible once they catch a whiff. This scene lures the creature in, invites it to lay down, and gives the coffin mimic an easy meal. If that doesn’t work, the shapeshifter isn’t shy to resort to violence. The coffin doesn’t just feed on the undead. Pesky heroes poking around in its hunting grounds taste just as good.


Macabre Vamp-Trap. As her fight against the vampires that took everything she had neared its in, La Contessa grew frustrated as they went to ground to wait out her wrath. While the alchemist took profane steps to prolong her life, she also bred further chemical-manipulated mimics to aid her fight. The most successful has been the coffin mimic. These wonderful abominations burrow into the dusty tombs where vampires and the like hide from the sun and set themselves up to resemble the other resting places. Then it is just a matter of temptation and patience.

Shapechanger.

TThe coffin can use its action to polymorph into an empty coffin 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 (Coffin Form Only).

The coffin adheres to anything that touches it. A Huge or smaller creature adhered to the coffin is also grappled by it (escape DC 15). Ability checks made to escape this grapple have disadvantage.

Blood Bloom.

Any undead creature that starts its turn within 10ft of the coffin must succeed on a DC 15 Wisdom save or be Charmed for the next minute. At the end of each of its turns, an affected creature may repeat this save with the effect ending on success.


Once a creature saves against Blood Bloom it is immune to the effect for 24 hours.

Swallow.

The coffin makes one bite Attack against a Medium or smaller target it is Grappling. If the Attack hits, the target is swallowed, and the grapple ends. The swallowed target is Blinded and Restrained, it has total cover against attacks and other Effects outside the coffin, and it takes 13 (4d6) acid damage at the start of each of the coffins's turns. The coffin can have only one target swallowed at a time.


A swallowed creature can attempt to escape (DC 15) as its action, exiting in a square within 5ft of the coffin if successful.


Creatures that are swallowed by the coffin lose their shapechanger trait, if they have it and revert to their natural form.

Frame Mimic

Rattling from the shadows, a gaggle of rat-gnawed bones march forward eager to slay the living. One of them lags behind, looking a bit more solid than the rest. You know your mace should have broken the leading skeletons to pieces. Yet, it merely cracked bones instead of shattering them. Tentacles lash out from the slower skeleton, adhering to you and pulling you closer to the maw manifesting from its ribcage. This is the frame mimic. The spawn of the ossuary mimic, this monstrosity also feels a kinship to the undead - specifically animated skeletons. It adopts a group of such horrors and its very presence temporarily empowers them. This is why the skeletons keep it around instead of hacking it to pieces as they would any other living thing. On top of that, frame mimics develop a supernatural stubbornness that can only be called boneheaded. So powerful is this force of will, that it mends their wounds as they plough forward against deadly spells. Frame Mimic Medium Monstrosit...

Brocade Mimic

The masked bard in gaudy attire was strumming away when the bar fight started. It kept playing even as chairs broke and mugs flew. Not one strum was missed even when blood was spilled. Then someone grew sick of the racket and stuck a hand ax into the bard's neck...with a wooden thunk. The fancy vest exploded with teeth, tentacles, and eyes. Then there was the color spray... The first brocade mimic lurked in the rafters of a bard college. Instead of eating a future player, it learned alongside them and caught a passion for the arts. Of course, it could have become an instrument but that wasn't quite grand enough. The mimic became a set of fancy clothes and was worn out the front doors. Sometimes it and its spawn become a bard's best friend. sometimes it pilots a dead one around for a bit, and other times it takes over a mannequin to strike out on its own. No matter how, the show must always go on. Brocade Mimic Medium Monstrosity (shapechanger), neutral ...

Yoke Mimic

Something tore apart the bandits you've been tracking, but it's not obvious what chewed and in some cases melted them. Maybe there's a wyrmling in the area? Either way, all that remains alive in the camp is a pair of oxen burdened by their cart. Though, they are quite nonplussed given the violence that must have occurred around them. Surely these simple beasts couldn't be the case of the carnage, could they? As you ponder this, the oxen start plodding away, pulling the cart of goods with them. Trying to stop them was the logical thing to do... their yoke coming undone with twin, yawning mouths not so logical. You know what that means... initiative rolls, please. Relatively benign, for a mimic, the yoke mimic was cultivated by an industrious farmer. They didn't see the point of wasting an animal that came into their care, even a strange monstrosity such as this one. It became a valuable tool not only to get fields plowed, but also kept the animals attached to it d...
