Been romping with my Undead until...

I think the reason that isn't or was overlooked was because most Banishments can't affect your sacred troops very well (They usually have higher MR). The blessing only affects your sacreds.

And astral is always a great pick for Ermor for a variety of reasons.

Well, after many hours i am kicking booty . I set my dominion at 9 as it seems apparent that is all the Undead need as opposed to supplies. My quality of units showing up is MUCH improved, and i'm keeping my cavalry separate as suggested as well as having my priest/prophet stocked with death gems and only casting power of sepulchre. The carnage is unbelievable ...no survivors, only death! With the Undead it's like the song goes: "gotta keep 'em separated" .
