Odd Thing

My favorite way to farm giants and other clumsy livestock is to cast Storm of Vengeance. It works well when outnumbered because at least one of them will fail their reflex save. That's the one I case blade barrier on. It chews away at clumsy while I slice up the more agile ones.

Except now when i try to case blade barrier I get a message that "magical energy is being used for other spells." I looked at the rules and update logs. Did the latest patch change things so that only 1 area affect spell can work at a time or am I on drugs? It seems like battle tide also interferes with blade barrier, creeping doom, and storm of vengeance. Not that clerics aren't already pretty tough, but spamming aoe damage spells was their best boss killing technique. I can see only letting one of each work so that they don's stack with themselves but I liked being able to make the screen about me a hellish place for large slow farm animals.
