Also, Energy Conversion can't be absorbing physical attacks on him unless Rich homebrewed something (immensely improbable in this case), since RAW it only works on attacks that "deal acid, cold, electricity, fire, or sonic damage."

That's why I said some form of energy conversion. Certainly he'd have to twist the spell a little - but since he's turning physical damage into physical damage, it doesn't seem unreasonable.

I recall in written words one of the Drizzt books by Salvatore, the Drow Psion had a spell that functioned exactly like would be required - you take physical hits that don't affect you, and you can channel that energy directly into any target you wish.
