Powergrace [Psionic]
You are more resistant to psionic powers than most people are.
Prerequisite: Must possess a
repertoire of powers.
Benefit: You gain a +1 bonus on all saves against psionic powers and psi-like abilities.
Special:
** You can take this feat multiple times, adding an additional +1 bonus.
So dip Erudite 1 and go Magic Mantle.
Then track down a smidge of Feater / Dilletante / PLZ's thingy.
