Sage Transformation

is a way of attaining Sage Mode, using a bodily reaction exhibited by members of Jūgo's clan. By exposing their special body fluids to natural energy, they gain increased physical capabilities and the ability to perform various shape-shifting feats.

Usage
This transformation is a multifaceted ability that permits them to achieve feats ranging from creating various weapon-like appendages to even consuming other human beings, as well as a general increase in their physical capabilities, such as in strength, speed, stamina, reflexes, perception and durability, along with improved power of techniques. Once transformed, common features include eyes with yellow irides and black sclerae, altered skin colour and longer hair (hair colour change may also occur in some users).

Variants

Trivia
