I don't think Ninja said that... Anyway, yeah there are rules. No God Mode of any kind, and no Character Jacking. You have to have REASONABLE (caps locking for any other recruits looking at this) weaknesses, so no "only this extremely rare dagger that I have" bullcrap. Newtons Law people: Every action has an equal and opposite reaction. Take that into account when fighting, recruits. Edit: Also, when Ninja said "No rules" in the op, he was referring to the ranking system before we had to close the dojo for a little.
