Wind Release: Wind Spear

The user flows chakra through all parts of their body, causing it to become noticeably greener, which increases their defensive power to its utmost limits by making the skin as hard as diamond. Furthermore, the destructive power of physical attacks is greatly increased, making this a great all-purpose technique. It can also act as a reflective shield, causing the attacks that hit them to deflect off of the skin using basic wind properties. The armor is especially strong against techniques but is weak to any  techniques.

A user with enough practice can use this to cover themselves partially (i.e. their hand and lower arm, and the side of their head) without using handsigns.
