::finishes readin the thread:: mmm....that event is very disturbing >.>
having to take somebody's arms to use a certain jutsu? sounds kinda Oro-ish imo o.O
anyways, i dont think that event is really necessary..basically all Deidara is doin is puttin his chakra in the clay to turn them into bombs...i assume the purpose of those mouths in his hands are to put chakra while at the same time shaping them into something.
now tell me how is that any different then just holding the clay in ur hand, shaping the clay into an animal or w/e and putting the chakra in it urself to turn it into a bomb? >.>
if u think about it, that's no different than gaara's sand ninjutsu where he puts chakra into his sand and make it turn into a clone, a hand, an avalanche, and live-size image of shukaku, etc
mmm...unlimited amt of clay...well there are some sites that tell you how u can make homemade clay so i think it's safe to assume that your character will be making more clay when he runs out...unless neji wants you to pay for it >.>
