Well, I read your post on the Top Ten characters thread Sei made, and I noticed how you mentioned something about almost all of Ryuns techs are linked together, through Sage Mode. Well, I want to completely redo my characters skills, so I was wondering: Would it be a good thing if I extended my various skills from the same source - as in expanding on what I already have currently?
Yes. Make a central ability or trait for your character. For Ryun it was his eyes, but centrally his Sharingan. From there, I tie everything back to the Sharingan. Even the techniques that don't require his Sharingan have some compliment to it. Check out my battle with Sei here. I know it's long, but if you read it, notice how Ryun fights: you'll see that he starts out, often, with a Sharingan-related technique and from then on out, every ability he uses either enhances that, or uses it to his advantage. In that fight's case, it was Susanoo and even though he used his Rinnegan more than his Sharingan, it all tied back to that Sharingan technique.
