Chakra Armour

Chakra Armour is a unique type of armour that drains chakra from ninjutsu and genjutsu while at the same time amplifies the wearer's chakra. A black-coloured prototype armour was worn by Dotō Kazahana.

This being said, the armour is also seen blocking and defending against thrown projectiles which require no chakra in the least, rising the question of what exactly their armour is based on. Perhaps there is a weaker ring of chakra set around them, only strong enough to block projectiles, while the armour absorbs the blunt of the stronger ninjutsu attacks.

Despite the advantage it gives the wearer, multiple wearers must be careful not to be too close to one another, as the armour is highly unstable and will explode on contact with another suit. The fact that this armour's main strength absorbs chakra also makes the wearer vulnerable to taijutsu. Also, Sasuke's Chidori was able to crack Dotō's armour, and Naruto was able to deal the blow that shattered its defence, suggesting that the armour has its limits in absorbing chakra.

Trivia

 * Bando, the primary antagonist of Naruto: Clash of Ninja Revolution 2, wears a variation of the Chakra Armour, which functions similarly as the Yukigakure version by reducing incoming damage and increasing attack powers.
