Methods that ignore SR?

[Dordledum]

Planar Handbook says Belker Claws is a "SR: yes" spell.

wasn't sure, but just checked the spell compendium and you're absolutely right.

Psionics are psi-like abilities as written in the EPH.
Psi-like=Spell-like b/c of default transparency in the EPH
Supernatural Transformation from Savage Species makes any 1 spell-like into supernatural.

All your psionics are now supernatural and ignore spell resistance.

Edit: @RUMBLETiGER: That quote is paraphrased from the PHB description of supernatural abilities. Look it up on the SRD for easy access.
