Neutralize Gas (Abjuration) (Air, Alchemy)
Level: 7
Range: 60 yds.
Components: V, S, M
Casting Time: 1
Duration: Instantaneous
Area of Effect: One 10-ft. cube/level
Saving Throw: None
By using this spell, the wizard renders inert and makes breathable any harmful vapors, gases, clouds, or fogs in the area of effect. This includes [[Stinking Cloud]] , [[Cloudkill]] , [[Solid Fog]], [[Death Fog]], [[Incendiary Cloud]], [[Acid Storm]], gaseous breath weapons, spore or mold clouds, and similar spells and effects.
Harmful gas or vapor is transformed into a common, harmless fog cloud of the same dimensions as the original effect, and then dissipates 1d3 rounds later. Creatures injured before the neutralize gas spell is cast continue to suffer any effects from their previous exposure—the spell does not heal or counter existing damage, so a creature currently choking and gagging from a [[Stinking Cloud]] receives no relief from this dweomer.
If cast in the same round of the effect’s appearance, neutralize gas can counter gaseous breath weapons, spores, and molds by allowing any creatures affected a +4 bonus to their saving throws and reducing any damage to one-half normal (save for one-quarter). Air-based or gaseous creatures are not affected by this spell; neutralize gas only clears the air of any harmful inhalants.
The material component is a bit of charcoal and some bark from a treant.
Notes: Uncommon spell (PO:SM).
