Well show me how to do it then
__
Pics and videos if you like also but descripe how it is made also.
Thinks of an idea as you are shooting the spike.
Now I want you to extend a bone out of each of your elbows. While at the same time extend one out of your knees. Plus at the same time make one out of your palms.
Nothing happens
More chakra to do this one. This requires three times as the last time you extended the bones from your palms.
Now come out with an attack to kill.
I like the move but it is confusing. Add more details on how you atrack and what you use to attack with.
All the attacks hit me and I go poof.
Nice job now time for some more training.
As I say this, I fall in front of you.
You know that wasn't me. Now since you got that down pack, try erupting bones all over your torso and arms. This is the technique that could be used a defense against earth jutsus and maybe even wind jutsus. This is also your best friend/enemy in battle at short range. The reason why it is your enemy is because it is a cheap move.
You fart and two bones come out of your chest.
Eww you stink. Now try more chakra and try to not use it all up in your fart and use it for your calcium.

Bones erupt out of your torso and arms
(Karamatsu no Mai) - Dance of the Larch
Rank: B
Type: Defence/Attack
Chakra Cost: 25
Damage Points: 40
Description: Karamatsu no Mai is the third of the five Kaguya dance forms. The User creates a mass of razor-sharp bone spikes all over their body. The user can grow these bones at an extremely rapid rate so they can stab an opponent even as the bones are growing. Since the Bones are harder than steel, they can be used defensively to block or trap an opponent's strikes.
This technique is a great surprise attack and it makes the user basically untouchable at close range. When an opponent is close to the user, they spin very fast, rapidly slashing the foe in multiple areas of their body.
Well that was great. Now it is time to peel back those fingers tips. Now try to shoot your finger tips. All your finger tips at the same time.
forgive my laziness I'll try harder now xdPoor description
Nothing happens
Just as I thought, nothing happens. Let us start off by concentrating chakra into our calcium in our hands then concentrate it into your finger tips and around it. Then using some of the chakra to peel your skin apart and burst out the finger tips.
