Rigor Mortis and Darkness?

[LordArioch]

Neither Arryn nor myself were bashing you, Argi. In fact I'll give you some advice.

Darkness is wonderful because 0 prec means few arrows and banishments hit your undead while they stumble forward, and with attack and defense penalties souless might actually be a match for living soldiers.

Rigor Mortis gives fatigue, and lowers stats that way also. Not as good, IMO, however, as C'tis you can make the artifact mask that casts it for free, in which case it is worth it. Perhaps try using with cold battlefield spell because undead are cold immune, to give faster fatigue and knock more enemies unconcious. Of course either one alone works if your army is large enough. Undead dont rout or get fatigued so you can hit them until they collapse and then kick them when they're down.
Darkness is still more reccomended.
