[AreaOfEffect]

First, wow PsiSoldier. I feel really bad you had nobody to show you that till now. I can't wait to see your reaction when you find out what the 'n' key does.

Second, your standard horror is a chump. They have no resistances, not even to poison, and their primary attack is useless against non-living beings. Just chucking animated undead at them will generally solve your problem. Ideally you want to cast undead horde so as to avoid a gap in your defense. Other body guards of use here are mechanical men and the like. They are more efficient because they don't feed the horror more HP on every hit with its life drain.

Third, as mentioned, horrors are chumps. Mixing in a good offense with your reasonable defense ensure better survival. AN spells like Lightning bolt and frozen heart make them go away real fast. Heck, drain them right back with Drain Life or leech. Succeed in fending off the horrors and the visit from a doom horror becomes a real unlikely event.

Trust me, I survived a good 40 rounds under the effect of astral corruption (and burden of time) as LA Man and I never got a single horror mark on my god and lost only 2 commanders to horrors. In one of those instances I got two horror attacks on the same mage in the same phase. He was scripted to cast returning, but only had enough gems for one casting. Just so you know, that sort of thing can happen.
