1. Keep everything non lethal. If you kill someone you will be hunted down by the Anbu. If it was accidental that shows you cannot control your skill and you get exiled from the village.
2. Now make sure when you duel someone you can only duel someone your own rank. If you PM me to fight someone a rank higher than you and I look over your skill and you wish to prove yourself I'll allow it if you can handle it.
3. NO cheapness in duels. Don't try to set everything in the area to your favor. We here in the tiger village like to be honorable fighters so keep it even with each other. You can use jutsus that affect the area of the fight, but use it when the fight is started for chakra consumption. So for example when someone is ready to fight you you can use something like hidden mist jutsus.
4. HAVE FUN
