Breathe Smoke, Dust, or Ash

This spell allows a character to survive in hostile, choking atmospheres, such as those on the planes of Smoke, Dust, or Ash. On the Prime Material as well as other planes, this spell allows the subject to breathe freely in areas that would normally incapacitate him due to thick vapor or particulate matter in the air. The subject of the spell is still vulnerable to magically created vapors, such as those generated by stinking cloud or cloudkill spells.

The caster can touch as many different subjects for the spell as he desires, but the duration is then divided up equally among the various recipients. The material component for the spell is a handful of pine needles.
