Swarm of Bilge Barnacles




Scuttering along one spindly legs, these crustaceans are covered with a white shells covered in a series of spherical clusters and spines. The middle of its shell contains a mandibled mouth ringed by tiny eyes, while the underside of its ‘head’ envelopes a leech-like mouth. Once they latch onto a creature, the shells slice up the flesh while the legs dig in deep. The clusters make it hard to dislodge the creatures, even more so as they convert a victim’s bones into additional shell.


Bloodborne Parasite. These foul beasts began as normal barnacles along a boat hull as the vessel sailed, and then sank in a noisome swamp. Instead of shriveling up and dying, these crustaceans adapted to survive. FIrst they latched onto lesser undead and drained their juices before being discovered by the Fiend of the Moors. The cursed ranger proceeded to breed and refine the profane creatures, gifting them with a thirst for blood only outdone by actual vampires. Like the other corrupted beasts in the Fiend’s domain, these swarms of bilge barnacles hunt the living and heed the risen elf’s call. Those that escape the feeding frenzy often succumb to the blood-born diseases that the barnacles carry.

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...
