That is some serious genjutsu. I wouldn't want to be caught in that. I'd rather get strapped to a cross and stabbed by Itachi for 72 hours... *awesome face**ahem* Halvtand and I have discussed this (a lot) and got sidetraked a bit (a lot (bewbs were mentioned)), so sorry it took us so long. We're thinking that this technique is like a mini version of opening a Gate, except the drawback is not quite as high next to the effect. So... *sigh* we agreed that perhaps instead of making it a custom technique, you should just make it opening a gate. He might not know that that is what he is doing (since the Eight Gates are forbidden techniques and all that), but it seems more plausible that way.(Haruka lost her chakra enhanced strength to Halvtand's logic, as well... She's opening a gate, too)Umm... I'm not sure what to say, here. You say that he's only mastered the wind element by 10% and is still at the leaf cutting stage, yet he is almost halfway at training a technique that uterlizes the element of wind. How can he train a technique that he cannot perform? How can he perform a technique that he has not even mastered the element for, yet? It doesn't add up. Until he has mastered the element of wind, he cannot train the technique.
I'll edit it to opening a gate. And I think there is some confusion. There are numerous times in the Naruto Manga where it is indicated and shown shinobi can use jutsu from an element they haven't mastered. Mastering an element only allows for enhanced power/ease of use in those Jutsu. In Ryuu's case, because he has not yet mastered Wind; wind jutsus require more chakra and are less powerful, but he is still capable of using them.
Example:
-Sasuke using the Fireball Jutsu when he was not even a genin. He had yet to train or undergone any devoted specialization to the Fire element. This can hold true for many Uchiha.
Also from Naruto Wiki: "This affinity makes it easier to learn how to create and control the nature in question, although even with an affinity this process will usually take any number of years. Shinobi are not limited to the nature they have an affinity to, though."
