This spell says it summons a Bearded Devil to fight a selected champion as part of a hell knight ritual. The spells says the Devil will use every means at it's disposal to kill the champion. I believe this would include using it's summon ability to bring into existence a second Bearded Devil. I have a friend who says that wouldn't happen as it is supposed to be a one on one fight. To me that seems to be pulling it's punches, as opposed to going all out. Can anyone provide meaningful advice?
