koichi's jutsus

bone shot: I shoot out spiraling bonetips from my fingers at the opponent. the tips are so sharp that they can go through flesh and bones

bone fists: i make boxing gloves made of bones around my hands, the bones are harder than tempered steel so it increases my fist damage.

kaguya's rage-when koichi gets pissed it is like another person takes over and his speed and strength are doubled.

earth bone: i stomp my feet to the ground then i shoot bones front my feet into the ground which enhances the earths strenth by two then the earth comes up out of the ground in the shape of spikes to stab the opponent.

bone healer: koichi places his hand on a ally or a fallen foe and a bone the size of a needle prickes them and injects a part of my bone marrow into them and it would heal any bone fracture or break

wow, this isn't a lot of abilties, you might want to add more and expand upon the ones you already have.

like the Great Crater, how is the crater formed? is it magic? is it ki/chakra based? is it terramancy?

what exactly do the bone gloves do to you or the opponent?

Actually no, you simply said the exact same thing as before. When it comes to stating your abilities, you have to be very informative about each technique and ability. This is for reasons that your list of techniques is legit and is not considered godhack. For instance, each of your techniques are too vague. If you need help, look at one of the higher ranked jutsu lists to get an idea of how yours should look. If you have any questions feel free to ask. Until then, edit please! Thanks...

Or look at my list. Itsg detailed as hell
