Hmmm, poison or cold are the two typical ways as they don't kill the soulless who respawn. Poison should work if you got something that has a poison cloud (bog beasts, hydras, etc.) as it'll still do enough damage through the poison resistance. I don't see anything terribly easy for C'tis to get, but you could watch for such opportunities. On the cold front, you could use the cold aura from a bunch of banes, but I'm not sure how well that would work in a heat dominion. Might be a job for the pretender, certainly powerful enough strategy to justify it and would only need to be done every few turns. A frost father pretender has a powerful enough cold aura (particularly if you take a couple levels of W and cast breath of winter) to punch right through a heat dominion, and he brings the aforementioned A for mass flight. On the other vector the mother of monsters brings a poison cloud and potentially the heft to put up gift of nature's bounty pretty early since you're b-lining enchantment (she can drop foul vapors to for a trivial cost). Heh, just make sure the lizard kings don't bless themselves if you've got heavy N on your pretender.
