Thought I would get this in ahead of time as a quick heads up on how mudras work before everyone manages to make idiots of themselves.

1.) Never repeat a Mudra, if you do it is a guaranteed derp.
2.) All single Mudra Ninjutsu will result in Fuma Shuriken.
3.) For two Mudra Ninjutsu : Any combination ending in Ten will be Katon, any ending in Chi will be Raiton, and any ending in Jin will be Hyoton.
4.) For three Mudra Ninjutsu : Any combination ending in Ten will be Huton, any ending in Chi will be Doton, and any ending in Jin will be Suiton.
5.) Again, Never, EVER repeat a mudra in any combination.

Remember these simple steps and you won't end up an lolDRG...err...NIN.
