Heatwave

Drawing on his combined studies of temperature and currents, an adept of fire and air can call forth a blistering wave of heat to sweep through his entire area. Adventurers caught in this heatwave will suffer fatigue, resulting in a loss of movement. Those who fail to save will find themselves greatly wearied, taking penalties to strength or dexterity and possibly growing very thirsty. The effects of heatwave are cumulative.
