Frightener (Su) Once per minute as a standard action, a greater poltergeist can temporarily drop its natural invisibility, revealing itself to be a grotesque, ghost-like humanoid. All creatures within 30 feet when a poltergeist uses this ability must make a DC 19 Will save to avoid becoming frightened for 1d4 rounds. The poltergeist then resumes its invisibility at the end of its turn as a free action. A creature that successfully saves is immune to the fear effect of that poltergeist for 24 hours. If the poltergeist's natural invisibility is negated via other methods, it cannot use this ability. Likewise, those that can see invisible creatures are immune to this special attack. This is a mind-affecting fear effect. The save DC is Charisma-based.
Rejuvenation (Su) When a greater poltergeist is destroyed, it only remains destroyed for 2d4 days. After this time, the undead spirit reforms where it was destroyed, fully healed. The only way to permanently destroy a poltergeist is to determine the reason for its existence and set right whatever prevents it from resting in peace. The exact means varies with each spirit and may require a good deal of research, and should be created specifically for each different poltergeist or group of poltergeists by the GM.Site Bound (Ex) A greater poltergeist cannot travel more than 120 feet from the point at which it was created or formed.
Telekinesis (Su) A greater poltergeist has no method of attacking apart from telekinesis. This ability functions as the spell telekinesis, with a CL equal to the poltergeist's Hit Dice (CL 8th for most greater poltergeists). A typical greater poltergeist has a ranged attack roll of +8 when using telekinesis to hurl objects or creatures, and can use the ability on objects or creatures of up to 200 pounds. If a poltergeist attempts to hurl a creature with this ability, that creature can resist the effect with a successful DC 18 Will save. The save DC is Charisma-based.
