Mathiok's Naruto Anime Mod Wiki

Description

Increases your damage with swords by around Strength 4 (+12-14 damage) 

Notes:

Extremely useful if you only have Kenjutsu to increase your damage as opposed to Boil Release: Unrivalled Strength, Lighting Release: Lightning Mode, Lava Release: Chakra Mode, or even just the Strength of a Hundred technique. 

It also costs a miniscule amount of chakra to maintain and activate as opposed to options listed above, and only kicks in when you are holding a sword, meaning if you're at a break in a battle you can change what you're holding in your hotbar and continue charging chakra.
