Resembling decomposing birds of prey, skultches are foul creatures that stand 3'-4' tall with 9'-12' wingspans.  Taught skin reveals their internal musculature, and bony spurs jut through their feathers.  They reek of corruption and decay.

Skultches are primarily scavengers, but they also have a particularly insidious method of hunting live prey:  they spit (up to a distance of 15', or sprayed downward while airborne) an oily fluid that, upon failure of a Saving Throw Versus Poison, causes the target to acquire the Prey Scent Physical Mutation Drawback.  They then take to the air and patiently circle high above their victims, awaiting larger predators to bring them down...whereupon the skultches descend to steal the spoils.  And flocks have been known to outright attack vulnerable targets.

They are immune to all known toxins and forms of disease.
