You’ll accept this Side Quest when you head to Saint-Arkh with your old Class VII members. Make use of Quick Travel and go to Isthmia Great Forest - Depths via West Sutherland Highway. Make use of the nearby monsters to build up your CP and then use the Resting Station before beginning the battle.

Grime Drome 19600 ☆☆☆☆ N/A ☆☆☆ N/A E - 40, WA - 100, F - 140, WN - 100, TI - 160, SP - 160, MI - 160 Bluster

Once you’ve began the battle against the Grime Drome you’ll want to take a look at your three new Brave Orders, Blue Ochestra, Valiant Hearts, and Zephyr Wing. For this battle you’ll want to keep Zephyr Wing active as it causes delay on the enemy as well as reducing recovery time for your party. Go to work on getting into the break status whilst weaving in Laura’s Lion Rush Craft to lower his STR/DEF, and then use any available S-Crafts to finish him off. During this battle if you find that you’ve taken a lot of damage, Elliot’s Holy Song Craft will be able to heal everyone for 30% HP.

Panic Wave can confuse your characters.

  • Nightmare Strategy

You’ll have an entire different party together for this battle so you’ll want to make use of their talents. To begin with, take note of their Brave Orders, all of these are very effective, especially Fie’s Zephyr Wing Order that will allow you to delay the enemies attacks while granting the useful Insight status to all of your party members.

Should you find yourself taking too much damage, Elliot’s Blue Orchestra can reduce damage while topping up your HP and using this along with his Holy Song to keep HP up and status effects off. Make use of Laura’s Lion Rush and Radiant Spin to debuff the enemy and then use Tri-Cyclone to attack the boss due to its high Break strength. As for the boss itself, it’s weak to Fire and all of the higher elements and it’s most deadly attacks will see you inflicted with Confusion if you’re not protected against it so be sure to cure immediately or the battle will go south quickly. As always, once the enemy is broken, make use of S-Crafts to put a huge dent into it’s HP.

Upon defeating the Grime Drome you’ll be rewarded with Dark Hair - Fie and Bluster, which gives STR+40 and doubles the duration of status affects when equipped.
