Might be a bit late, but I once ran an interesting Honorable Duel variant. One of my players wanted to ask a proud warrior race...entity a bunch of personal questions, but said entity wanted to take their measure in a fight. So the agreement became this: A duel fought until one can no longer stand. The last standing heals the fallen. All magic and weapons allowed, as long as they are one's own. No pulling one's punches permitted. But most importantly: Each damage-dealing weapon or spell strike is a question, asked and answered from attacker to target. So the true goal of the duel is not to down your opponent, but to land as many damaging strikes as possible without holding back or downing your opponent too quickly. A demonstration of your control and mastery, of both mind and body. It turned out pretty great!
