Well, I was thinking...
Deidara hardly ever threw just one clay lump at someone. So, I was thinking about a Mass Explosion Clay jutsu that would hit every enemy in the room, centering on the targeted enemy. It would be a higher level jutsu with a chance to hit everyone else in the room as well, not just enemies.
I would say a way to code it would be to use Mass Explosion to use one part of a lump of clay and then use regular Clay Explosion for another, and have Mass go off when Clay Explosion does with the added damage and chances.
It was just a thought.
Also, I wanted to propose a restringer. I know I put it up on the boards as an idea but...hell, this just seems more open to discussion.
I wanted to propose a restring blacksmith in a room under the weaponsmith of old konoha, so that he's accessable to everyone. Make the restring tokens 50 MP each or something and let people make their own names, so that it'll add more originality to the characters, rather than making everyone have the same mission equipment, y'know? Everyone having Deidara's pouch...seeing people pull things from it can be old. This will also promote customization and RP within the mud.
Both Ideas are, as always, open to discussion. THey're clay waiting for the mold ;D
