I admit that this idea concerning the jutsu duration is certainly difficult to put in place if only one person -ie the GM- has to handle duration of all jutsus of different kind for characters of different levels. Maybe each player could handle their own jutsus that way ?<br/><br/>Still, I agree for now we have not been confronted to such a problem, and I would rather see common sense solve the question of jutsus duration than the use of a rule. It was just a point I wished to raise to avoid further possible issues. Let's push it aside for now.
