SRD:Tower of Iron Will

You generate a bastion of thought so strong that it offers protection to you and everyone around you, improving the self-control of all. You and all creatures in the power’s area gain power resistance 19 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 is 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.
