Rikujin Shinka Ritual

The highest collaboration ninjutsu performed by the Twelve Guardians. It is also considered a kinjutsu since once used, it drains the chakra of all the Twelve Guardians.

Overview
By resonating their chakras, the Twelve Guardians combine their chakras into one monstrosity. In terms of power granted, Rikujin Shinka makes the Twelve Guardians 100 times stronger than than those who had opened all the Eight Gates power of the Eight Gates Released Formation. Rikujin Shinka is only active for ten minutes at a time, making it a last resort jutsu.

Drawbacks
Rikujin Shinka has many drawbacks. In exchange for resonating chakras, the Twelve Guardians are rendered immobile as their chakra resonates. Once expired, the Rikujin Shinka drains the Twelve Guardians of their chakra, leaving them vulnerable. Once used, the Rikujin Shinka cannot be used again for one week, allowing time for the Twelve Guardians' chakra to replenish.
