This spell banishes feelings of weariness. For the Duration, the subjects take 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 subjects take 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.
