This piece of equipment does not count towards armor total, like everything else it can be stolen. It is also the only item which can boost chakra reserves:
Name: Historiband
Appearance: A simple headband made of black cloth and a simple iron plate for the user to etch their alliance into.
Rank: B
Coverage: Forehead
Special Abilities: This headband will give the user an extra boost in chakra adding five percent of their total chakra into them. It can function as a battery of chakra or combined with the user's. It is also very durable but only defends where it is placed. Not only this but it also blocks off their chakra so C rank and below sensory jutsu cannot find them.
Descriptions: This is a Staff Reward item and as such a bit different.
Origin: This was found in a box by the ninja whom it is rewarded to. The box was found during their journey on the side of their path. It beckoned to them with a burst of chakra light, and the wearer will now feel that same burst of chakra.
