Plague Storm

You create a hideous gray cloud, similar to fog cloud, that occasionally crackles with foul-smelling bolts of sickly green lightning. Creatures in the area must make a Fortitude save or contract one of the following diseases: blinding sickness, bubonic plague, cackle fever, mindfire, or shakes (the disease is chosen by you when you cast the spell and applies to all creatures that fail the save). The disease is contracted immediately (the onset period does not apply) and is an instantaneous effect. The victim also takes a –2 penalty on saving throws against diseases. Unlike a fog cloud, the plague storm moves away from you at 10 feet per round, rolling along the surface of the ground. Blinding Sickness effect: 1d4 Str damage, target must make an additional Fort save or be permanently blinded Bubonic Plague effect: 1d4 Con damage and target is fatigued Cackle Fever effect: 1d6 Wis damage Mindfire effect: 1d4 Int damage Shakes effect: 1d8 Dex damage
