Thespian Aura (aura, emotion, mental, occult) 30 feet. The muse phantom inspires a supernatural emotional response—either comedy or drama. Each creature that begins its turn in the aura must attempt a DC 20 Will save; on a failure, the creature is affected as long as it remains within the aura. If the muse phantom is emitting a comedic aura, affected creatures become clumsy 1; if it is emitting a dramatic aura, affected creatures instead become stupefied 1. The muse phantom can change its aura from comedic to dramatic or viceversa, or cease or activate this aura, by spending a single action, which has the concentrate trait. A creature possessed by a muse phantom is immune to this aura.

Grand Finale [>>>] (mental, occult) Requirements The muse phantom's thespian aura is active; Effect The muse ceases its thespian aura and deals 4d8 mental damage to creatures in a 30-foot burst, including the creature it is possessing, if any (DC 22 basic Will save). Creatures that fail their Will saves are fascinated by the muse phantom for 1 minute. The muse phantom can't use Grand Finale again for 1d4 rounds.

Muse Possession [>>] The phantom muse attempts to possess an adjacent corporeal creature. This has the same effect as the possession spell (DC 20), except the duration is 1d4 hours, and since the phantom muse doesn't have a physical body, it is unaffected by that restriction of the spell. If the target is at least trained in Performance, the DC of this ability is 24.
