FFXIV Eureka Orthos Unlock

How to Unlock FFXIV Deep Dungeon Eureka Orthos

With Final Fantasy XIV Patch 6.35 now live, a new Deep Dungeon is available for players to tackle. Like previous Deep Dungeons, there are certain requirements that need to be met in order to unlock FFXIV’s Eureka Orthos. While one of the initial requirements is relatively simple, two others are gated by Main Scenario progress and having any combat Job Class leveled appropriately.

The requirements to unlock the Deep Dungeon Eureka Orthos in FFXIV are as follows:

  • Players must have completed Main Scenario Quest “Endwalker”
  • Clear Floor 50 of Palace of the Dead
  • At least one Level 81 combat Job Class

Once these requirements are met, you can talk to Koh Rabntah in Mor Dhona at X:21.8, Y:8.1 to unlock Eureka Orthos.

The Eureka Orthos Deep Dungeon in FFXIV is a great place to level up any Job Classes from level 81 to 90 as well. Like Palace of the Dead, and Heaven on High, it offers experience to players for completing a series of floors. With each floor being more challenging than the last, it’s also engaging side content for those looking for something extra to do. Especially since you can run it by yourself or with a dedicated group.

Final Fantasy XIV is available for the PS4, PS5, and PC. Patch 6.35, which includes Eureka Orthos along with other side content like the Hildebrand Adventures side quests, is now available.
