The Staff

From Inga no Kusari wiki

The Staff is Finn Green's Glint.

The Staff is a small golden pin badge in the shape of an equilateral triangle. It is worn on Finn's chest, in between and below the badges of The Stream and The Scale. On the face of the badge is the engraved image of a serpent coiled around a staff, and each corner has engraved on it a smaller equilateral triangle.

Glint Ability

The Staff combines the abilities of The Stream and The Scale, and also enhances them. Through the use and channelling of Finn's own reiatsu, he can not only restore the sound minds of others, but also, by touching the affected area, he can heal wounds and other kinds of damage. The power of these combined badges is not strong enough to heal missing limbs or any other such serious damage, but it can easily cure cuts, gashes, bruises, minor illnesses and poisoning.

The Staff can cure most cuts and bruises in a matter of seconds, larger or more severe injuries take longer to do, the power shorts out and after one minute and thirty seconds of healing. If the power shorts out, the wound will still be healed as much as is possible during the time, but repeat exposures will do nothing (the rest of the wounds reparation will rely on the natural healing process of the victim).
