Oh, so is it possible to 'debuff' people without actually having a debuff ability? Such as stab them in the eyes and blind them, or strike them in the chin and disorientate them?

While I'm at it...Seeing how this is pretty much a game, would an Avatar with abilities centered around being an underdog (does more damage against opponents higher level than them) be allowed? Or would it sorta break the whole point of levelling up?
