|Literal English||Rock Armour|
|Anime||Naruto Shippūden Episode #59|
|Classification||Ninjutsu, Chakra Flow|
This technique makes earth-chakra flow through the body, absorbing the properties of stone around the user to form a skin-deep armour that is transparent and is only visible when light reflects off it. Despite encasing the user's body, the armour has no apparent affect on the user's speed or agility. The armour is shown to be able to defend from all forms of blunt-force trauma. At the same time, it enhances the user's strength for more powerful physical strikes and break free or through restraihjynts and walls. Because this jutsu works by constantly absorbed earth properties, it requires no extra chakra after initiating it, yet still needs a sufficient amount of stone to be performed. While powerful, it is highly absorbent and too much water will eventually affect the user's mobility and reduce its defensive might. Also, if in a muddy terrain, the user's excess weight can lead to sinking under.
