SRD:Thought Shield

You fortify your mind against intrusions, gaining power resistance 13 against all mind-affecting powers.

You can manifest this power instantly, quickly enough to gain its benefits in an emergency. Manifesting the power is an immediate action, like manifesting a quickened power, and it counts toward the normal limit of one quickened power per round. You can use this power even when it’s not your turn.

Augment: For every additional power point you spend, this power’s duration increases by 1 round, and the power resistance it provides increases by 1 point.
