Natural Invisibility

A poltergeist is naturally Invisible. It becomes visible only when it uses Frighten.

Rejuvenation (divine)

When a ghost is destroyed, it re-forms after 2d4 days within the location it's bound to, fully healed. A ghost can be permanently destroyed only if someone determines the reason for its existence and sets right whatever prevents the spirit from resting.

Effect The poltergeist makes a telekinetic object Strike against the triggering creature.

Frighten (concentrate, emotion, fear, incapacitation, mental)

Requirement The poltergeist must be Invisible.

Effect The poltergeist becomes visible, appearing as a skeletal, ghostlike humanoid. Each creature within 30 feet must attempt a DC 33 Will save, becoming Frightened 2 on a failure. On a critical failure, it's also Fleeing for as long as it's frightened. On a success, the creature is temporarily immune for 1 minute.

At the start of its next turn, the poltergeist becomes invisible again.

Telekinetic Storm (concentrate, occult)

The poltergeist telekinetically throws numerous small and jagged chunks of stone rubble, either spreading them out among multiple foes or directing them at one target.

When this effect is spread out among multiple foes, the poltergeist makes a telekinetic object Strike at a -2 penalty against each creature within 30 feet. These count as one attack for the poltergeist's multiple attack penalty, and the penalty doesn't increase until after all the attacks.
When this effect has only one target, the poltergeist makes a telekinetic object Strike against the target, and the damage increases to 6d12. It deals 2d12 damage on a failure, and no damage on a critical failure.
