A ring that uses its user's anger to increase their attack power. Wearing the ring instills great anger, and blinds the wearer to fell all enemies in sight until none are left standing. The ring releases its wearer from its vice once all enemies are felled, returning the wearer back to their senses, so aside from battle, wearing it doesn't cause any dysfunction among those the wearer mingles with.
Fury Ring automatically provides the equipping character with Berserk. This allows it to improve the strength of the character equipping it, but renders them uncontrollable. It can be bought in Gongaga Village for 5000 gil, or the Battle Square for 2560 BP.
