This spell banishes feelings of weariness. For the Duration, the subject takes no penalties from the fatigued or exhausted conditions. The effect of invigorate is merely an Illusion, however, not a substitute for actual rest or respite. When the spell ends, the subject takes 1d6 points of nonlethal Damage, along with the return of the original condition(s). A Creature can be under the effects of only one invigorate spell at a time; if it is cast a second time on that Creature, the first effect immediately ends.
