While the time, place, and fighting method can vary wildly, there are several rules that apply to any juris macto:
- Challengers choose the time and place for duel. The person challenged chooses how the fight will happen - typically sword and fury.
- The person challenged may choose a champion to fight in their place. The challenger may not.
- The Master of Arms informs everyone of the combat rules, inspects the weapons (for poisons if they are not allowed), and allows the participants the opportunity to explain why they're fighting and one last chance to back down from the fight. Barring this, the participants then take ten paces away from the Master of Arms as he or she counts. The Master of Arms then signals and combat begins.
