Ectoplasmic Miasma (CR 9)

Source: Pathfinder #43.

Swirling clouds of spirits congealed into a single ethereal mass often haunt the scenes of particularly gruesome slaughters. Bound together in death, these confused souls know nothing more than to strike out at the living, their faces stretched into silent howls and mad shrieks.

EFFECT

Dozens of spectral visages coagulate in a swirling miasma of mangled limbs and twisted, howling faces. The congealed apparitions swiftly pass through the bodies of those within the area, duplicating the effects of both solid fog and acid fog (save DC 17), but dealing untyped damage.
