hmm
if Auto-Quicken still has the 9th level spells pre-req, it's basically Battle Blessing, just way later. Allows known action abuse.
Epic Ex.Know. blurs the original 6 types of Psions a little.
Epic Psi Focus doesn't catch up to what metamagic does.
Psi Improved Heighten, doesn't have the tricks of non-psi. EStP would save 1 feat via this, if the build is even possible.
Improved Manifestation still orders of magnitude less than recharge.
Improved Metapsi is already in CPsi as non-epic.
Improved Spell Capacity adapted, see heighten above.
Power Knowledge nice especially for non-9s, but see the EZbake Wizard.
Psicrystal Power, supermount's lobotomized baby brother says thanks.
