A fearsome chittering heralds the approach of this morbid monstrosity. A giant headless scorpion-like thing of blackened bone and chitin rounds the corner ahead, scuttling along the wall as its two pincers snap ominously. A long, grisly tail composed of dozens of chattering skulls arches up over its back. Some of the skulls are ancient and bleached white, while others are recent trophies still shrouded in rotting cheeks, their jellied eyes rolling madly in their sockets. A curved bony tip protrudes from the last skull of its tail, its deadly point smeared with poison.

A skull ripper is an expert at collecting its favorite trophies—skulls. Once it has pinned a foe, it can attempt to behead the victim with a single gut-wrenching rip of its claws. This attempt is made as part of the grapple check to maintain an existing pin, and if successful, deals 4d6+18 points of damage to the victim. If this damage is enough to bring the target below 0 hit points, the victim must succeed at a DC 23 Fortitude save to resist having its head torn from its body, which results in instant death for most creatures. The save DC is Strength-based.
All creatures within 30 feet that can see a skull ripper must make a DC 18 Will save at the start of their turn in order to avoid becoming frightened for 1 round. If the victim recognizes any of the heads affixed to the skull ripper's body as having once belonged to friends or allies, that victim takes a –4 penalty on the save.
