I have made a mistake and forgot about Corren's rapier… while Corren may not know that it is magical I think the encounter with the golems might give him reason to believe that it is as it does bypass their resistance although I don't think he actually hit (You are remembering to add in the +1 bonus on attacks correct?)… Corren's rapier is a +1 magic weapon.
Oops this should have been posted to the support thread.
