Earth Release: Earth Spear

The user flows chakra through all parts of their body, which hardens their skin to a steel-like quality. This increases their defensive power to the utmost limits. The user's skin becomes much darker, an almost black color. Furthermore, the destructive power of physical attacks is increased, making this a great all-purpose technique. The amount of techniques that can break through the areas hardened by the Earth Spear are close to zero, not including its undeniable weak point: Lightning Release ninjutsu. Kakuzu used this technique through the use of his earth-element mask.
