okay.
*Facing towards the training dummy with his 'feet' planted on the ground, I start by gathering my earth chakra into my right leg before, stomping my right foot onto the ground and channeling it into the ground. I then, manipulate and change the structure of the ground, causing a circle that has a one meter radius with short earth spikes, each 5 cm long and emerge around the dummy which is the first layer, followed by the second getting closer and the last emerging under the dummies feet, piercing through them. I try the other and do the same thing as before, only this time I weave a single hand-seal(I'm assuming its snake?), having the spikes fire upwards from the ground in the form of projectiles that hit and pierce through the dummy.*
So, like other spike techniques I can have this emerge on any ground source or another earth technique and have them attack at an angle?
