Breathe

The spell completely clears the target's respiratory system for a fleeting second, giving the momentary, revitalising sensation of breathing perfectly clean air. For the most part, it causes absolutely nothing, unless the target is afflicted with a respiratory ailment or confronted by inhaled fumes, smoke or the like. In this case, it suppresses the effect for only one action.

As might be horrid for spellcasters with unfavourable respiratory conditions, this spell, inexplicably, cannot be used on self.
