ABOUT

Damned soul swarms that have fed on the vitality of many mortals, or whose constituent souls retain a strong sense of self, become large and cunning predators. These horrors resemble a churning cloud of scowling faces in a variety of colors that flicker through a numerous hues, allowing them to blend in with their surroundings or become altogether invisible. They enjoy engulfing several opponents at once, and can overwhelm the senses of those they rake with their spectral claws. This large cloud of ghostly claws and screaming faces shimmers in a variety of colors, like a swirl of oil on a rain puddle.
