Well, I could blow some feats to advance my effective turning level, but that's not really worth it any time soon since it only ever applies to the undead.  Not a rare demographic, mind, but still quite constrained.  I do have those two spells that can pump up turning considerably, and those advance with caster level (a priority to boost anyways), which is good, but requires the expenditure of spell slots.  Thing about Turn Undead, though, is that it's such a bizarre and wonky mechanic to begin with that it's rather hard to fix.  I'm not sure what to do on the matter, nor of how much is even worth doing.  By and large, I'm already planning on using most of my turning attempts to fuel Domain Spontaneity anyways (though if you want to toss me a few more instances for free, I'm all for it).
