Alright pretty simple.
*walks over to lake and holds up right palm*
Just focus chakra into your palm and form it into a flat-ish disc, then skip it along a surface. Each bounce releases a ripple of chakra, until it reaches the target and hits them.
*throws the chakra across the lake, each skip cause a big ripple in the water, until it reaches a big rock in the middle, it hits the rock and leaves a much bigger crater than expected*
You can also charge physical objects with the chakra for the same effect, like a rock or a shuriken.
Next one.
*walks over to a big boulder*
Stomp your foot, and then instead of releasing the ripple outward, you bring it into your own body, controlling it and compressing it as it radiates up your leg, then it grows as it goes through your torso, and then you compress it again and force it through your arm. By the time it reaches you hand its very condensed. Palm thrust your target, release the ripple, boom goes the dynamite.
*stomps and palm thrusts the boulder, completely shattering it*
Questions?
LA, I taught you this CFS, right? xD
