DESCRIPTION
As you sweep your arm in front of you, superheated air rushes forward and slams into your enemies, leaving them sweating and gasping for air.
Heat Wave sends an intensely hot gust rolling over the battlefield to crash into enemies and sap them of strength. The effect takes the form of a 35-ft.-by-35-ft. square directly in front of the caster with one side centered on them, and it deals 3d6 nonlethal fire damage to everything in its area with a Fortitude save for half as well as to resist becoming Fatigued. Any creature already fatigued that fails its save becomes Exhausted, and any creature already Exhausted becomes Staggered.
Creatures with the Fire subtype are immune to the spell's effects, and creatures with the Cold subtype or that are wearing metal armor take double damage with a -4 to their save.
