[Saxon]

I thought regen didn't work on undead, like my Carrion Dragon or a Banelord? Let me give it a shot!

That said, it looks like I will be able to dominion them out. I have been pushing hard to keep the carrion critters coming and am slowly overwhealming C'tis. They are also on a long peninsula and I am taking the ocean around them and building temples. Hitting them from both sides should help. The game is taking a long time, the higher level of difficulty has made the AI pretty good.
