The spell description for wail of the banshee in-game, in the Layonara campaign handbook, and in the NWN manual all say that the spell affects "all enemies within the area of effect".
I've heard from other players, however, that the wail will affect friendly people, as well (in Layonara). I found a thread in which Tathnolu describes an instance in which he did not cast it for fear of killing another party member, which also leads me to believe that is true.
So, my question is: does wail of the banshee affect party members, or only enemies within the AOE?
Thanks.
