Acid fog

Acid fog, also known as death fog, was an conjuration spell that created acidic vapors.

Users
Acid fog could be cast by sorcerers and wizards, as well as clerics who commanded the Water domain.

Effects
The spell was similar in effect to a solid fog spell, but the mists it produced were also highly corrosive to any creature or item caught within it.

Components
Like solid fog, a casting of acid fog required a mixture of a pinch of powdered hoof from some animal, and a pinch of powdered dried peas.
