It would be interesting to have a wizard pass himself for a cleric. Get into a soft, woolly white robe and sandals, clean shave, work on your most pious look, yes, those lovely Bambi eyes, you got that right, and, yes, wear a cross. You can strap a mace if you want (you don't have to wear armour, say steel gives you a rash).

The say the Lord grants your prayers for "death from above, 6 times a day" :)
You can even summon Angels if you want (oh, well, not exactly the Metatron...)
