1) Done

2) I need a cooler way to say "much bigger fireball". Xp It's not like Shiro can do anything close to that magnitude. Right now the boost his cloud chakra gives isn't even noticeable. How much the technique is boosted depends on the amount of cloud chakra that is added to it. My idea was that if another ninja uses X amount of chakra to make, say, a fireball, and if Shiro adds Y amount of cloud chakra, the total power of the new, much larger fireball would be X+Y, or simply the sum total of the chakra used. Theoretically, a Cloud user with enough chakra could take a minuscule amount of a basic nature element chakra and increase its power many times over using the harmonizing aspect of their cloud chakra, but Shiro is a [i]long[/i] way from anything like that.

Given that Cloud Release is a Kekkei Tota (Cloud Release : Support :: Dust Release : Blowing shit up with extreme prejudice), I don't know what other sensory ninja would be able to compete for the title of "most skilled sensory ninja in the world", which is why I made them all but extinct, for the same reason the Dust Release is limited to two people in the canon. The Yotsuki are now just boring old "renowned" sensory ninja.

The sensing emotions only goes so far as being able to tell a person's general mood, such as if they are sad or angry or happy. It's full application would be to tell when another person is lying, which is something Shiro would never forgive. 

What if the cloud sensory technique was reduced to just general emotions, sensing the presence of individuals and chakra, and recognizing known chakra signatures? It would only work to sense things that are in contact with Shiro's cloud chakra.

3) Done, though I'm not sure how they differ.

4) Harmonize! The word I couldn't think of was harmonize. The special trait of cloud chakra is that it [i]harmonizes[/i] with chakra of other natures and harmonizes with the emotions of those it touches. This was really bothering me.

I think Shiro version 1.2 is all edited and done. What do I need to fix now?
