Oki day... Here is what the cleric does: sanctuary, then scroll on self. Mage can cast TS if he wants. He can't do crap for spell damage, so, thinking himself frightfully intellgient, he summons a plethora of enemies. Laughing all the way, the mage sits and waits for TS to end and the foolish cleric to die. However, the cleric wearing boots of speed just runs away from the summoned enemies! Then, he casts another scroll of antimagic on the mage, and runs away until the summoned morons are gone.
Animate dead doesn't last long enough I don't think...
Even still, the cleric can outlast the mage this way and eventually pound him into goo.
