User blog comment:Martialmaniac/Kurapika's index chain/@comment-10528819-20151028011210

I would say that what Kurapika's really lacks is a defensive tecnique, Holy Chain can heal him however healing and defending are two completly different things since you could be killed of in one hit where Holy Chain wouldn't be helpfull. Maybe his index chain serves as that as a protective technique that allows him to cover himself with chains so they would serve as an armor.

Or it could be used in a fight where he needs to protect someone and maybe the index chain could be used for that, maybe by the same "armor" I said before
