ops,i was confusing with C2(but this is a good ideia for C2),but how about the Giant Zombie(hidden in Minecraft code) with the player skin that walk and when gets in contact with something explode(or maybe with a certain key?)
well, you can just make this a larger version of yourself and then when you want it to kill, it turns into microscopic clay mites that incinerates all animals that are in it. You should be able to see this if you can see chakra(sharingan, byakugan, rinnegan).
It would be much better if you didn't have to craft the deidara move's such as the clay spiders and clay birds. The should be a mana bar and to use jutsu it will cost a certain number of mana like a RPG system you can upgrade how much mana you use your health and other things
Deidara starts with 100% health and from 100% to 80% he uses C1 then when you get his health down to 80% to 50% he uses C2 50% to 25% he will use C3 and finally 25% to 1% then when you kill him he explodes the lower his health gets the better his moves showed be
I agree. There should be that if he ever gets to only 1 health left, he uses C0.
