Sage of All Things

Overview
Traditionally, the Jugo are unable to use ninjutsu outside of Sage Mode, as far as we know at least. We can chalk this up to the fact that their chakra system is a tangled mess of natural energy and standard chakra as well as the body's reaction to natural energy which results in Stage 1 and 2.

Through rigorous training a Jugo can master the Path of a certain nature. For example a Jugo may master the Path of Storms. The paths act as another Stage 2 but allow access to Nature Based Jutsus while still following the general theme of transformation. For example a Wind Path Jugo can create a Wind Release Cannon.

Each path acts as a nature in the bio so a genin Jutsu could only learn one path and so on. The Path replaces Stage 2 but a Jugo can still choose to enter standard stage two if they please. The Paths also constantly drain the user of their chakra, they are also unable to recharge in a Path Form and as such will revert to an exhausted normal state if they run out of chakra.
