How do I fight ermor?

[jaif]

The dominion was solid in my borders. At the edges, it was give and take, and in the Pythian provinces it was coming along (some to my side, some still pythian). Dominion wasn't really a problem. The problem was that when he attacked, he hit an outlying province on an island chain, then hit other provinces up the coast. By the time I tossed him off the coast and fought my way back down the islands, the Last province was completely depopulated.

I'm wonder if I had used the raven-something spell (ravens eat corpses and bring back gems) much earlier if that would have slowed his growth.
