Explosion clay ( Deidara from naruto )

You have the ability to incorporate it into clay to then have it explode. You create explosions by mixing earth and thunder chakra natures. 

Your chakra is equivalent to your level x3 +5, and using your explosions takes 1 chakra for every 1 square ft of an clay you want to fill with explosion chakra. For every one 1ft of clay you can make a 3ft explosion in a ball radius.

You can also shape it into different shapes, and figures, to then have those figures come to life, like an explosive clay cat, or at Higher levels an explosion dragon.
