Force of Will

(Expanded Psionics Handbook, page 46, DnD 3.5)

[General]

You are able to resist psionic attacks with extreme force of will.

Prerequisite

Iron Will

Benefit

Once per round, when targeted by a psionic effect that allows a Reflex save or a Fortitude save, you can instead make a Will saving throw to avoid the effect. The benefit of this feat applies only to psionic powers and psi-like abilities. This is an exception to the psionics-magic transparency rule (see page 55).

Special

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).
