Hunt 07: For Whom the Wyrm Tolls
Ring Wyrm - Rank III
You can access this Hunt as soon as you have defeated the Wyvern Lord, which is part of Hunt 08: A Scream from the Sky. The difficulty with this fight stems from its high HP, but it’s easy to complete after Larsa rejoins your party and you visit Eruyt Village and can purchase the 
Decoy spell.
Petitioner
Balzac, who you can find in Lowtown. He was previously called a “Rabanastran” and is the guy sitting on the crate on the west side of Lowtown.
Mark Location
The Ring Wyrm is located in the Dalmasca Westersand area, far to the west, in an area called the Windtrace Dunes (check the map of the Dalmasca Westersand to find it). It will only appear during a sandstorm, though, so exit and re-enter the area until a sandstorm appears, and then search the south side of the zone.

The biggest challenge you will face while attempting to defeat the Ring Wyrm Mark is dealing with its massive amount of HP. It will also use “Restore” on itself to gain back 30% of its HP partway through the battle.
Make sure that you have a tank setup to deal with Ring Wyrm’s damage – check the party setup page of the Tips and Tricks section for more information. Have one of your party members set up with a Gambit to keep 
Protect on your tank and to keep 
Blind on Ring Wyrm. You should also have an Esuna Gambit setup to cure your party members of negative status effects, as it may hit you with Sap, Immobilize, and Disable throughout the fight.
Ring Wyrm is weak to Fire-based Magick spells. Not only are Fire and Fira quite effective, but Belias, your newest Esper, uses Fire-based attacks and is also quite an effective tool to use during this fight.
