Earth Release: Earth Spear

To activate this jutsu, the user first flows Earth chakra throughout their body either completely or partially. This causes a noticeable discoloration, as the affected skin turns to a dark black. Overall, this enhances the character's destructive power, while also granting them an immense level of protection from almost all attacks aside from Lightning Release techniques to which it is very vulnerable to.
==Limitations==
The use of Earth Spear grants two extreme benefits to the user, including their physical strength and durability. With the former allowing the user to blow through most defenses, and the latter making their skin "as hard as diamond". Without relying on advanced methods of attack, the only reliable way to break through Earth Spear is with Lightning Release jutsu.
Using this jutsu only applies to specific parts of the body. At the cost of more Chakra, this effect can be extended across the entirety of the body. The exact level of what's covered is defined by the word "appendages". This traditionally means parts of your body such as your head, an individual arm, and leg. In this context, it will also mean one's chest, as well as what was mentioned before. So in total, there are 6 appendages that this can be applied to. Covering one appendage with Earth Spear costs 4 points of Chakra. Therefore, to cover the entire body for a single round to avoid damage would cost 24 points of Chakra.
