Erastone

Erastone was a ring Teigu previously wielded by Honest.

Abilities
Erastone was shaped as a golden ring of average radius. When activated, a purple eye opened in its center, with black branching patterns appearing around the eye itself. Once its user chose their target, the ring shined a bright light towards a designated Teigu, disabling and destroying the weapon. However, the weapon had a singular usage, as the ring's eyeball would shatter once its effect had been utilized. It is unknown if this ability can be reused or if the damage to it was permanent.

History
During the Revolutionary Army's rebellion, Honest used Erastone against Leone to simultaneously destroy her Lionelle and his ring, but it failed to save himself even after fatally shooting the Night Raid member who crushed his skull. Teigu de Honest
