Emperor's Champion

At the start of any Assault phase that the Champion is in combat, he may issue a challenge. Your opponent must choose an enemy character to fight him who is involved in the same close combat. The challenge may not be refused. Move the models into base contact and fight out the close combat as normal. No other models may attack the Champion or his opponent. The outcome of the challenge decides the outcome of the close combat; only the wounds they inflict on each other are used to determine which side has won.
