Scasm
The brownish, silent beast before you bears barbed tentacles and two small, eyeless heads on its shoulders. Even its scaled head seems to have no visual sense organs.

Special Abilities
Chew (Ex) Scasms pre-chew their food before putting it into their primary mouth. A scasm can deal damage with each of its bites when it makes a successful grapple check against its opponent or opponents.
Devouring Bite (Ex) A round after a scasm has chewed on an opponent, the target it transported into its primary mouth as a free action, where a successful grapple check deals 1d8+4 points of piercing damage.

The ravenous predators known as scasm are quick to spread in uncivilized environments. They are vaguely reptilian masses of tentacles, teeth and tumorous flesh, endlessly seeking meat. These eyeless beasts seem to be mindless raveners, ceaselessly roaming in search of prey, but they are more intelligent than mere animals. Small packs of them seek to surround likely food sources, apparently sensed through vibrations felt in the air through their paws, and irregular protrusions in their hide. Their many attacks can quickly bring down even seasoned troops engaged to root them out, and they will strip downed prey to the bone.

They reproduce through fission, and it is when a scasm is ‘budding’ that they will lair for a short while, the ‘parent’ recovering its strength and the ‘child’ expanding quickly into the large mature form. Eating a single humanoid or livestock animal such as a cow will spur the budding process. It is lucky for frontier society that scasm are also rather prone to cannibalism when denied a regular food source. Packs over a half-dozen scasm are seldom found, and only under a particularly fit specimen that is capable of recognizing the worth of pack hunting.

Scasm are typically silent, communicating with one another through a semi-organized thrashing of their tentacles and mouth-stalks.

On Porphyra
Scasm are especially rampant in Nor-du-Mag, where magic is not available to check their spread. Their sandy color nearly matches the umber stone and gravel of that wasteland, and packs of them roam the terrain, both above and below ground. It is said that ash giants there have found some way to whip the beasts into some form of practical use.
