Almost all fights in @Ninth Circle Arena are assumed to be non-lethal, and most bouts in the @Eighth Circle Arena are non-lethal.
In the @Fifth Circle Arena , @Sixth Circle Arena , and @Seventh Circle Arena combatants can choose to participate in non-lethal bouts. These prize fights pit two honorable combatants together in a contest. Usually, a contest of strength but most times a battle to knockout. Certain traditions only exist in these circles as a contest of pure strength between two combatants. The @Sumo are the primary participants in this contest. A non-lethal Sumo contest is played on the center of a 15-meter diameter ring, each combatant only task is to push the other combatant out of the ring or knock them prone. The one still standing is the victor.
When two combatants agree to participate in a non-lethal fight, they can agree on the terms of the contest: Knockout, Sumo, or the player/party can suggest another contest. Simple strength contests can be as simple as arm wrestling. Simple Dexterity contests can be akin to a game of chase/tag or a footrace. Contests that test a persons constitution could be holding a large weight for longer than the other opponent. Contests can even be suggested that test a players intelligence or wisdom if the player/party suggests an option. Every once in a while the various Arena Ringmasters might have a bout of insults and jokes to curry favor with the audience, engaging in a contest of charisma! The Ringmaster Insult Battles are how Ringmasters get "promoted" to higher rings.
