Our unwritten list
1. No drugs
2. No alcohol
3. smoking is done outside (not currently a problem since nobody in the group smokes)
4. Just because a player bought/owns a given supplement does not entitle its use. The decision as to what, if anything, will be allowed is up to the current GM.
5.Cocked dice or dice that fall off the table are rerolled
6. No powergaming (defined as showing no interest for anything outside of combat and complaining when the game moves away from combat) or munchkinism.
7. Character improvement (e.g, gaining new skills, multiclassing into a new class, etc.) must take into account in game events/experiences and availability of training (when appropriate).
8. Character knowledge and player knowledge are two seperate things!
