How to unlock the Eureka Orthos deep dungeon in FFXIV
Explore the new deep dungeon in Mor Dhona
Similar to the other deep dungeons, you can keep your aetherpool gear by exchanging Orthos aetherpool grips. If you’ve strengthened your Orthos aetherpool arm and armor to +10, and you’ve completed the sidequest “Rage Extinguished,” you can synthesize an Orthos aetherpool grip which will reduce the strength of your aetherpool arm and armor by 10.
