I think just PotS,
I first thought that do, I brought a fair amount of indie priests, so initially I figured they were casting it, but once I saw my main mage "BALBLABLABLABLABLABLA" (that's his name
) casting banishment I was surprised.
Than I thought the tarts, or his troops weren't in range, but than I measured the battlefield and they were in a 10-15 range distance from the communion masters.
