I feel the anima it too iconic for us to be locked out of. However while I forget the details of it Earthscorpion gave out rules at some point about how using the mote reactor is exhausting which means means characters can only run it for so many scenes before being unable to function. At stamina 2 she would probably collapse after a single scene of using the full anima, or even the mid power version. I believe it was stated that this was one of Keris's weaknesses in Kerisgame.
So the scene should go something like exaltation->kick ass->nap time.
No, Hinata definitely has the anima. It's just that generally the anima peters out on its own without any negative side-effects (other than being out of motes). It's learning how to harness the mote reactor that requires pushing yourself to withstand your own True Power
TM.
Hmm.
With her style, training Dex to 5 would be a good thing too.
I should point out, Ninja can seemingly break the 5 dot limit on Attributes, as Lee has no jutsu, and 'definitely' as more than ten dots in Strength/Athletics.
Also, Dojutsu probably count as mutations that raise Perception by (at least) 1 dot, with other special abilities.
Well, I was going to avoid commenting on my thoughts for this kind of stuff, but... fuck it.
Having some kind of Attribute Excellency for Physical Attributes and maybe a halved one for Mental Attributes could make it work. Maybe a Excellency System using committed motes instead of spending them if you wanted to keep them cheap(er)? Would probably need to be comparatively weaker. Or a hybrid maybe, the motes used for the excellency are split so they're half-spent and half-committed.
The Chakra network being some kind of upgradable mutation increasing your mote pool as you train it, have Jutsu have a Handsign keyword and be able to buy the 12 Handsigns as cheap Charms only requiring awakened essence (or a Chakra Network if you're making them separate things).
My current very tentative thought process is to combine
@Crilltic's Princess of Blades Chakra Rating system (shinobi are rated 1 to 10 in terms of threat) with
@yrsillar's Forge of Destiny Enlightenment system. In sum, the higher rated you are on the chakra rating system, the more automatic successes you get against those of a lower rating than you are, with exponential advantages the higher you go. This would neatly model how a kage-level shinobi basically renders grunt shinobi irrelevant and would prevent me having to give kage some absurd attributes in order to model them.
To give you some idea of how it'd work, the Forge of Destiny system has three divisions in between each major increases in rank - low, mid, high - and between low, mid, high there's a single auto-success difference between each. So, for the purposes of Naruto, a high chuunin fighting a low chuunin would get 2 auto-successes against them. If you increase an entire rank, however, the difference becomes twice as large. A low jounin fighting a high chuunin would have 2 auto-successes over him, and a high jounin fighting a low chuunin would have 10 auto-successes over him. This doubles again if you go up yet another rank. A high jounin fighting a high genin would have
24 auto-successes over him.
Now, of course, these rankings are not the official ones - Naruto was a kage-level shinobi masquerading as a genin for like 99% of the series, and skill-wise Neji's already the equivalent of a chunin.
For Lee, there'd be an equivalent Physique Rating system. Chakra Rating would be far more important (not sure how yet), but for every rank up in Physique you get to expand the limits of your physical dice pools. Also, probably, some vague nods at speed: every rank up your speed increases by some vague formula that basically means 'goes real fast' and, every physique
rank difference (not division) against an opponent means you get to act two ticks to their one.
The Eight Gates permits you to forcibly increase your physique rating, with the final gate permitting you to literally rank yourself higher than the highest rank - but only for X actions and then you die.
But, like I said, I'm not great at mechanics, the numbers are there to give everyone a general idea of what's going on. Also, these auto-successes only apply to individual combat: social combat remains an even playing field save for the bonus willpower having a higher ranked chakra rating gives you.
All this remains quite tentative.
