Six Paths Senjutsu

The Six Paths Sage Technique is a technique which drastically empowers all of the user's abilities to a far greater extent by utilising the combination of senjutsu and tailed beast chakra.

Overview
The user's physical strength, speed, stamina and regeneration are exponentially increased. The user also gains the ability to use senjutsu and fly, as well as use chakra arms and create multiple Truth-Seeking Balls (although the Truth-Seeking Balls aren't always necessarily linked with this technique). Apperance-wise, this form creates a pattern of Rinnegan and nine tomoe on the user's back, as well as cause the user to grow horns on their forehead. Upon obtaining this, the user gains complete control of all 5 basic nature transformations and Yin–Yang Release.
