I stumbled upon a possible bug in a hibernian keep yesterday. The outer doors were down and we were in front of the inner doors. After targeting the keep (con green) I could use the mana drain spell on the keep. My pet could attack the point in melee, too - it's located in front of the inner doors in the courtyard. I tested around a bit and found out that one mana drain could fill my whole mana bar. That can't be intended, right?
