As apopsi, except that 4d4 powers are permanently deleted if the target fails a Fortitude saving throw (with a DC adjustment of -10).
By using this power, you delete 1d4 powers permanently from the subject's mind. You specify the level of each power, and the game master randomly determines which of the subject's powers is actually deleted. Psychic chirurgery or reality revision can be used to restore the lost powers, but it must be performed within 1 week of losing the powers.
50 XP per level of the deleted powers.
