lch:

I did plenty of tests on big groups on premade map. Used scouts and ktonian necromancers. The only thing that helps was protection and luck [of course besides high HP or shroud with S9 bless]. Robe of Shadows didn't help at all. Fire Plate on 0 prot unit was enough to decrease deaths on 9 HP units by about 75%.

P.S. I doubt there is any fire damage involved. I tested with fire plate just because fire gems are cheaper than earth. And I could easily make lots of them with Forge to protect some mages.
