Eureka Orthos.png
In the late Third Astral Era, when the ancient Allagan Empire was at the zenith of its glory, researchers toiled deep under the Crystal Tower to uncover secrets which might uplift their motherland to even greater heights. Their laboratory was dubbed Eureka Orthos, where impossible concepts of immortality, cloning, and dominion over the divine were made reality. So fantastic was this research that the legend of Eureka has endured through the ages, and now you have been tasked by the archmagus Noah to bring the laboratory's buried secrets into the light of day.

Req. Level 1
The billowy plumage of the fledgling Phoenix─a legendary bird that, upon each fiery death, is said to rise from its own ashes in a literal “blaze of glory.” When placed upon the body of one who is incapacitated, it will instantly revive the person. While some cultures insist that the tailfeather's restorative properties trump those of down, these claims have yet to be proven in any sort of scientific capacity.

※Cannot be used during battle.

Entering Eureka Orthos

Players can enter Eureka Orthos by speaking with Khatun in Mor Dhona (X:34.8 Y:19.2). When entering as a party, only the party leader can start the instance. It can also be entered with a cross-world party.

  • All party members must be in the same Mor Dhona instance to enter Eureka Orthos.

Players who have cleared floor 30 of Eureka Orthos and the sidequest "Rage Extinguished" will be given the option to start from floor 1 or floor 21 when creating a new save file. When starting from floor 21, players will be set to level 90 and their inventories will be cleared of protomanders and demiclones.

Fixed Party

  • Players may enter with a group of up to four players, with no restrictions to classes, jobs, or roles.
  • After speaking with the Wood Wailer expeditionary, select "Enter the Eureka Orthos," then choose an unused save slot. Next, select "Enter with a fixed party."
  • All future forays into the Eureka Orthos must be done with the party members and party composition chosen upon registering.
  • To enter solo, enter as your chosen job or class as a fixed party.
  • Your character's level, aetherpool arm and armor strength, inventory, and floor progression will be recorded.
  • Players in a fixed party must have uniform save data. Moreover, this save data can only be used with the party members and party composition chosen when first entering the Eureka Orthos.

Matched Party

  • Similar to the Duty Finder, players may choose to be randomly matched with other players on the same data center.
  • After speaking with the Wood Wailer expeditionary, select "Enter the Eureka Orthos," then choose an unused save slot. Next, select "Enter with a matched party." All future forays into the Eureka Orthos must be done with the class or job chosen when first registering.
  • Matched parties will always be comprised of four players.
  • When registering with less than four players, any open party slots will be filled automatically.
  • Players in matched parties are free to choose any composition of jobs and classes they desire. It is not necessary to register with the same players each time, however, you must use the class or job you selected when first registering as a matched party.
  • Your character's level, aetherpool arm and armor strength, and floor progression data will be saved.
  • Players will be matched with party members who have the same floor progression saved. In order to be matched, players must enter with the same class or job that was equipped when progression was first saved. Furthermore, aetherpool weapons and gear strength must be above the requisite for the given floor.
    Players can join a party in progress by first checking the "Join Party in Progress" box in the Duty Finder menu, then speaking with the Wood Wailer expeditionary.

Rules, Dungeon EXP & Actions

  • Players will start at level 81 regardless of their current class or job level. By defeating enemies that appear in the dungeon, players will be able to gain EXP and level their characters up to 90. Your Eureka Orthos level is not directly related to your level outside of the dungeon.
  • All enemies players encounter in Eureka Orthos will give a fixed amount of EXP regardless of the number of members in your party or the difference in level between you and the enemy. Rested experience and experience bonuses will also be ignored.
  • Players must reach the required level in the dungeon to have access to level restricted actions and statuses. Players can gain actions and statuses regardless of whether or not they have completed the necessary class or job quests.
  • Players who have entered the deep dungeon with a class will be restricted from using any job actions.

Recording Progress

Boss enemies will appear every 10 floors. Upon defeating them, players will be able to record their progress, at which time they may choose to leave the deep dungeon. Please note that progress made in strengthening aetherpool arms and armor is saved independently and shared across all save data.

Aetherpool Gear

  • Players will be restricted to the use of an Orthos aetherpool arm and Orthos aetherpool armor when inside Eureka Orthos. In addition to gaining levels, players must enhance these items as they progress through the dungeon.
  • Normal gear has no effect on your character's attributes inside Eureka Orthos, and Orthos aetherpool armor will take the appearance of your current gear upon entering the instance.
  • Aetherpool gear strength will not carry over from Palace of the Dead or Heaven-on-High.
  • Aetherpool gear can be enhanced by accessing silver coffers, which appear randomly on each floor and after defeating certain enemies.
  • When enhancing gear, there is a chance of failure that varies depending on the current level of your gear and the floor where the silver coffer is found.
  • Aetherpool gear can be enhanced to a maximum strength of +99.
  • In the event the strength of your aetherpool gear exceeds the maximum allowed by your current level, its attributes will be synced.
  • Aetherpool gear (any gear equipped upon entering the instance) is not subject to durability loss, nor can it gain spiritbond when inside Eureka Orthos.

Protomanders

  • Players will, on occasion, obtain protomanders from treasure chests within Eureka Orthos. These items have various uses ranging from displaying the entire map of your current floor, to providing party members with beneficial effects. Up to three of each protomander can be held at any time. These items can be found in a shared inventory to be used by all party members.
  • Some protomanders offer different effects from the pomanders found in the Palace of the Dead and Heaven-on-High.
  • Normal items such as potions can still be used independently of this shared inventory.
  • Pomanders cannot be taken outside of Eureka Orthos and when in a matched party cannot be used after the completion of a set of floors.

Extension:DynamicPageList (DPL), version 2.3.0 : Warning: No results.

Demiclones

Players will, on occasion, obtain tomestones from treasure coffers in Eureka Orthos, which can be used to generate demiclones. These items can be used by all party members once acquired.

Up to three tomestones can be held at once and are kept in a shared inventory. Tomestones cannot be taken outside of Eureka Orthos. When in a matched party, they cannot be used after the completion of a set of floors.

Demiclones will follow and fight alongside the player who generated them. Each demiclone has unique strengths, so choose carefully to turn the tides in your favor.

Navigation Map

A special navigation map will be displayed, which can be used to progress through the rooms on a given floor. When any party member enters a room on the floor, the map will automatically update. The icons for the Cairn of Return and the Cairn of Passage will appear in their location on the map.

  • Players can display or hide the map by pressing the M key. This is the same key for the Hold button to lock the map in position.
  • The default navigational map will not be displayed in the Eureka Orthos.

Moving to the Lower Floors

Parties progress to lower floors by activating the Cairn of Passage stones. These stones have three phases, and will always be inactive when arriving at a new floor. Players must defeat the enemies that appear on the floor before the stone can be fully activated. As the phases progress, the color of the stone's icon on the map will change, and the perimeter around the stone will glow when it becomes fully activated.

Floor 31 and Beyond

While floors up to 30 are related to the story of Eureka Orthos, all floors after were created strictly as a challenge for players. For this reason, you cannot enter floors beyond 30 with a matched party. Furthermore, in addition to completing the sidequest "Rage Extinguished," players must meet the following requirements to challenge these floors:

  • Start from floor 1 or floor 21 with a fixed party and clear up to floor 30.
  • Party KO count must be zero.

Save data with one or more party KOs cannot be used on floor 31 or higher.

  • Please be advised that the party KO count will also increase in the event your party abandons the duty or logs out while inside the instance. again.

Resurrection

In addition to resurrection items and actions, players can use a Cairn of Return to raise all KO'd players. These stones, like the Cairn of Passage, have three phases of activation and can only be used when fully activated. The stone will be inactive when arriving at a new floor. Players must defeat the enemies that appear on the floor before the stone can be fully activated. As the phases progress, the color of the stone's icon on the map will change, and the stone itself will glow when it becomes fully activated.

Traps and Floor Effects

As players progress, they will arrive at floors with traps that will be set off when walked across. These traps are invisible unless a player has a special item which can reveal their locations. In addition to traps, some floors have the below effects which may benefit or provide some challenge to the player's ability to progress:

  • Some floors may inflict detrimental or beneficial statuses on players.
  • Some floors may prohibit certain actions.
  • Some floors may have strengthened enemies.

Treasure Coffers

There are three types of treasure coffers which will randomly appear somewhere on the floor at the same time as enemies. While most of these coffers will give players various benefits, some will have traps, such as surprise enemy attacks.

Gold Coffers

Gold Coffers may yield protomanders. The coffer will remain even if these items already exceed the inventory limit.

Silver Coffers

Silver Coffers will strengthen Orthos aetherpool arms and armor. However, opening these coffers will have no effect if the players' weapons and gear are at their maximum level of strength. In addition, even if players' weapons and gear are not at maximum level, there is a possibility that the strengthening effects will not take hold even after opening the coffer. Weapons (including shields), and gear will be strengthened individually, and depending on the player.

Leaving the Eureka Orthos

If all party members are KO'd inside the Eureka Orthos, they will be removed from the instance.

  • Unlike other dungeons, players cannot choose to return to the floor entrance if they are KO'd.

Management of Save Data

Players can manage their save data by talking with the same NPC you talk to in order to enter the Eureka Orthos.

Resetting Progress

Players can reset their level and progression to floor 1. However, aetherpool arm and armor strength will carry over to the new file. This means players can reset and return to floor 1 to continue strengthening their weapons and gear if they have found that previous progression became too difficult.

  • Reset save data cannot be recovered.

Disbanding a Fixed Party

Players can convert fixed party saved data to matched party saved data. Aetherpool arm and armor strength will be carried over, but pomander information will be reset. Under these conditions you will be able to be matched with other players who are currently playing on the same floor as you.

  • If any members of a fixed party are unable to enter the Deep Dungeon after the deletion of save data or usage of the World transfer service, they must select "Disband your fixed party." to carry over their save data.

Rewards

  • If your job or class is level 90 upon entering you will receive Allagan tomestones and gil.
  • If your job or class is between levels 81 and 90 upon entering you will receive Experience points, gil, and Allagan tomestones of poetics.
