Octopus Sage Mode

Sage Mode is the result of using natural energy along with a ninja's normal chakra in perfect balance to drastically empower their abilities.

Only signers of the Octopus summoning contract can learn this variant.

Usage
A prerequisite to being able to use senjutsu is that the user must have a large reservoir of chakra themselves in order to manipulate the natural energy.

Overview
Octopus Sage Mode is a form of Sage Mode that is taught by the Octopuses of Myōkuroidōkutsu. Once attained, this affects the user's body in a number of ways by catalyzing certain permanent, physical changes. As this has only been attained by Tasogare so far, it is unknown if any of these changes are unique to his physiology or if they are present for anyone.

Advantages
There are numerous advantages to Octopus Sage Mode. These include:
 * The user's physical strength, speed, stamina, reflexes, and durability dramatically increase.
 * The user's ninjutsu, genjutsu, and taijutsu become more powerful.

Disadvantages
There are a few disadvantages while using Sage Mode. These include:


 * If the user draws in too much natural energy in the attempt to initiate Octopus Sage Mode, they run the risk of turning entirely into ink in a manner that cannot be reversed.
 * In order to gather enough natural energy to initiate the transformation into Sage Mode, the user must remain perfectly still. Because of that, the user can be an easy target for an opponent.
 * Because the user needs to move during combat, the senjutsu chakra cannot be replenished, which means the user can't stay within this state for extended periods of time though; it can be stretched.
 * After Sage Mode has ended, the user appears to experience exhaustion.
