Hostile Mind

 
Prerequisite(s): Cha 15+
 
Benefit: Whenever you are subject to a power from the telepathy discipline (regardless of whether the power is harmful or beneficial to you), the manifester must make a Will saving throw against a DC of 10 + 1/2 your character level + your Charisma bonus or take 2d6 points of damage. The benefit of this feat applies only to psionic powers and psi-like abilities. This is an exception to the psionics–magic transparency rule. You cannot take or use this feat if you have the ability to use powers (if you have a power point reserve or psi-like abilities).
