The Ring Wyrm is a Rank III Mark from Final Fantasy XII. It is powerful despite its low rank. It is the seventh mark listed in the Clan Primer and becomes available after the player vanquishes the Wyvern Lord. It can be found in the Windtrace Dunes area of the Dalmasca Westersand during a sandstorm. Defeating the Ring Wyrm is an early way to get the Icebrand sword.
