How do i make a rasengan?

My goal is to make the best naruto game on roblox. I know how to make it, like the handle and the daage, but how do u do the animation and how do you make it so that if the rasengan hits someone, there is a sphere of wind around the target like friazas game.

Its simple, Just go to the models and Search "Rasengan" If you may contain a full rasengan script. Just find it properly
