Pernicious Poltergeist

You create an echo of a powerful poltergeist, temporarily anchoring it to the area to terrorize and harm any opponents foolish enough to remain in the area. Because the poltergeist is a manifestation and is not truly present, it can't be attacked or hurt; it remains Invisible unless otherwise stated. When you Cast the Spell, and the first time you Sustain it on subsequent rounds, the poltergeist creates your choice of one of the following effects.

• •Deathly Assault (negative) The poltergeist focuses on one creature in the area and flies through that creature's space, dealing (4 + scaling)d10[void] damage (fortitude save).
• •Frighten (emotion, fear, mental) The poltergeist becomes visible, appearing as a skeletal, ghostlike humanoid. Creatures in the area must attempt a will save, becoming Frightened 2 on a failure.
• •Telekinetic Storm (force) The poltergeist hurls debris and quasi-real objects around in the area. All creatures in the area take (4 + scaling)d8[force] damage (reflex save).

Heightened (+2) The damage of the deathly assault effect increases by 1d10, and the damage of the telekinetic storm effect increases by 1d8.
