While risk fighting is a player-driven activity and doesn't have specific in-game rules, players often establish their own rules or restrictions to ensure fair gameplay and minimize disputes. Commonly agreed-upon rules include: 1. No use of certain items or equipment, such as overpowered weapons or armor. 2. No use of healing items during the fight. 3. No interference from outside players or additional combatants. 4. Agreement on the specific combat area or location for the fight. 5. Agreement on the consequences and terms of the fight, including the agreed-upon items to be risked.
