[Kōton: Hepaisutosu no te] Steel Release: Hands of Hephaestus
Type: Offensive/Defensive/Supplementary
Rank: S
Range: Short - Mid
Chakra: 40
Damage: 80
Description: After performing the hand seals Tiger → Horse → Bird, the user will form two large steel hands that burst forth from the earth. The hands are extremely useful for offensive or defensive measures. These hands are large enough to protect the user 360 degrees around them and they are extremely hard and can crush bones with one strike. The hands can extend up to mid range and can mimic the user's actual hand movements such as grabbing or punching. Due to the chakra within them, they can perform either the Steel Release or Greater Steel Release Technique.
Notes:

While controlling the hands, the user can't perform any other techniques other than the Steel Release and Greater Steel Release Techniques which must be performed through the steel hands.

Usable three times only

The hands are useless after 3 turns .
[Kōton: Uni no ikari] Steel Release: Wrath of an Urchin
Type: Offensive/Defensive
Rank: A
Range: Short - Long
Chakra: 30
Damage: 60
Description: The user releases a burst of steel chakra from all over his body. As he does this, a multitude of spikes will emerge from his skin, forming a spiky outer shell synonymous to a sea urchin. The user will then release the spikes in a omnidirectional assault that will send a barrage of senbon like spikes that are sharp enough to penetrate through objects in its way due to its density and momentum. Due to its steel nature, the spikes are strong enough to penetrate through targets/objects of greater density such as earth constructs of A rank or lower.
Note: Usable only 4 times in battle.
Yeah, so I've never done this before (I think :\), so for now just ask me any questions you want answered about these techniques and I'll try my best to answer them.
