Frost immune Devils?

[Boron]

Staff of storms + Wrathful skies , Falling frost , thunderstrike .

Storm demons do also wonders .

Best counter would be Storm + Wrathful sky caster with mech men teleported in . The mech men hold the line and protect your Caster(s) and the wrathful skies + thunderstrikes do kill the devils rather quick .

An AQ alone could maybe also kill the devils if you teleport in a 2nd mage wearing staff of storms , then casting only wrathful skies and then retreating .
If the devils get buffed seriously , mainly the 50% SR spell , Regeneration + Weapons of Sharpness 300 devils can rather easily kill your AQ no matter how you equip her .
