The wizard's Universal School and the Cleric's Magic Domain have virtually identical first level abilities. If you have both you simply have a choice of Wis bonus or Int bonus.
My "I'm too magical for you" spell-geek Mystic Theurge is unhappy. (Lay off the MT, k? I had 40ish spells in my head at level 11. DM never knew what was coming.)
I realize it's an RP decision to take the Magic Domain, but I was hoping there would be a caveat allowing a player to combine these two effects, maybe up to making touch attack as a sort of Spectral Hand.
(Why, yes, I was Main Healer because our Cleric refused to wear plate.)
