Ya, Curse of midnight wind is a exceedingly useful power for shutting down KB. Another technique that I tested out was having a errant unit (9 strong)with command + errantry banner charge a 10 strong black knight unit with command while they were under effects of various powers (As I was curious how errants would do) Excluding having ALL of the buffs/debuffs active, having either ice shard or curse of anraheir and curse makes the errants much more of a contender, let alone if you get both off along with curse of midnight, then they need 5's to hit and rerolling 6's, making almost impossible to really get hit, let alone wounded or KB

If you get locked with realms, your odds look slightly better, as you only need either iceshard or anraheir to go off for them to hit on 5's plus curse of midnight making them reroll 6s.

Beasts + Heavens = bad times for the enemy
