Sentient Poltergeist (3.5e Feat)

Wizard-level Version: As above, and two of the following: Special: This feat may be taken again in order to gain two more of the extra Wizard-level bonuses.
 * Automatic Escape: When the inhabited item is destroyed, the Sentient Illusion may transfer to a touching item without taking an action.
 * Better Item Senses: The Sentient Illusion gains 120' Darkvision and 30' Blindsense while inhabiting an item.
 * More Control: The Sentient Illusion gains a 10' perfect fly speed and can use itself much as though it were a creature wielding the item, with a Strength score equal to its Charisma score, and a Dexterity score equal to its Wisdom score.
 * Haunt House: The Sentient Illusion may inhabit an object that weighs more than a number of pounds equal to 3 times its character level, so long as the object does not occupy more than one 10' cube per character level.

Fighter-level Version: As Rogue-level version, but Enter Item becomes a standard action.

Monk-level Version: As Fighter-level version, but lose Voice and Senses, except touch.
