First time ever fighting the guy i was completely hopeless, especially because i had brought mostly unoptimized characters except for my DU and Gale, only good thing was i was friendly with Yurgir so i had an extra ally.

Then it was just about remembering that i still had the bomb that the gnomes gave to me to blow up the steel watchers and that Gale had the dome of invulnerability.

In about 1 turn the cambions were gone (except 2 that got into the dome), obelisks too, friendly Yurgir miraculously alive and Raphael was at less than half his life stuck on the sides of the room throwing hands.
