Hmm... Ria's nothing like Sasuke.

I'd go for 3 instead then which Blade suggested cuz IMO Chuunin level, not that I'm pushing it. Since rule #1 never compare a canon character to an AU character which I think Hillan said or you said. Just as others have said, use common sense.

Ria is an AU and Sauce is canon, two different characters and different strengths and weaknesses . I have learned to not imitate the canon character. AU character is different but boundaries are still intact. Just because one can do more, doesn't make it entirely better than the original. Quality(The Sauce cuz Prodigy) > Quantity(Ria from the AU).

So I got 3 tips:
Gowi's "When to use it."
Blade in terms of rank.
Buddha's common sense.

It all adds up!

So yeah, I will go as 1 would tire her, 2 would tire her more, the 3rd would break her which leads to almost putting her out. In short, it all depends on how it is used from here on out. Make a 4th one and dies.... as to Kakashi's make a 3rd one and die.

If this is fine with you.
