Okay let's begin with the first technique.
(Doton No Jutsu) - Earth Release Technique
Rank: D
Type: Attack/Defence
Range: Short-Mid
Chakra cost: 10
Damage Points: 20
Descripton: Creates small pillars of earth, small tools, and small shields of earth
Alright for a D-rank technique, I love it. It's such a great and handy technique. What I want you to do is use your newly created doton chakra and send it towards the ground, once it is in the ground. Use shape manipulation on the ground, the chakra should have merged with the earth, giving you small control over it. From that I want you to create a simple pillar in front of you, shouldn't be more then about 3 meters tall, once you have completed that I want you to gather up your doton chakra again. But this time in your hand, and use shape manipulation on the chakra again to form into a earthen kunai in your hand that you will throw at my clone.
Good thing about this technique, you can make a pillar for example underneath you to push you up into the air, or for an extra boost of speed if you explain it correctly.
