Completing the Underkeep Dungeon Guide for Final Fantasy XIV

Select Language:

The Underkeep is a level 100 dungeon that was added in Patch 7.2 of Final Fantasy 14. As the party searches for information regarding Calyx and the Endless Queen Sphene, they venture into the depths of the Everkeep, which houses the ancient Alexandria castle.

Unsurprisingly, Calyx and Sphene have activated the castle’s defenses. Players will need to battle through machines and hostile creatures that now inhabit the remnants of the castle. Here, we’ll explore how to unlock this dungeon and successfully defeat its three bosses.

Unlocking The Underkeep

To access the Everkeep, players must complete the Main Scenario Quest "Descent to the Foundation," which can be started by speaking to Shale in The Backroom of Solution Nine (X:6.0, Y:6.3). This quest is the sixth one introduced in Patch 7.2.

Note: A minimum item level of 705 is necessary to enter this dungeon.

Boss Fight: Gargant

The Underkeep’s first boss is Gargant. The battle area features four tube-like pathways that are separated by cascading waterfalls of sand. Keep these pathways in mind, as they will play a significant role during the fight.

Here’s a breakdown of Gargant’s attacks:

Attack Name	Type	Details
Chilling Chirp	Roomwide AoE	Affects the entire party. Be ready with AoE healing.
Almighty Racket	Line AoE	Gargant faces the arena’s center and deals damage in a large line AoE directly in front. This attack appears briefly before executing, so players should move quickly.
Aerial Ambush	Line AoE	Gargant crawls along a tube and hides behind sandfalls before jumping through, dealing damage in a line AoE. Observe its movement to predict its next position.
Earth Spikes	Circle AoE	Inflicts damage via large circle AoEs that occur shortly after Chilling Chirp and alongside Almighty Racket. Players should dodge both sets of the spikes.
Sedimentary Debris	AoE Marker	Targets players with AoE markers. Spread out to prevent overlapping, which happens simultaneously with the second wave of Earth Spikes.
Earthsong	Circle AoEs	Summons two sets of Sand Spheres that explode in small circular AoEs. Move to a safe spot to avoid their first and second attacks. The first occurrence will pair with Aerial Ambush, requiring careful tracking of the boss.
Trap Jaws	Tankbuster	Delivers high damage to the tank; defensive cooldowns are advised here.

Gargant’s mechanics may seem simple individually, but they can become complicated when combined later in the fight. Pay close attention to Aerial Ambush; failing to track Gargant properly can lead to significant damage.

Boss Fight: Soldier S0

The second boss in the Underkeep is Soldier S0. Here’s a summary of its abilities:

Attack Name	Type	Details
Field of Scorn	Roomwide AoE	Deals damage to all party members.
Thunderous Slash	Tankbuster	Inflicts high damage to the tank.
Sector Bisector	Half-circle AoE	Generates afterimages with blue half-circles indicating attack zones. Only the last afterimage will attack, so players should move to the opposite side of it.
Ordered Fire	Line AoEs	Cannons in the arena deal line damage from two corners, intersecting and leaving the opposite corner safe. This will occur simultaneously with Static Force.
Static Force	Conal AoEs	Attacks each party member with moving conal AoEs. Players need to spread out to avoid overlapping, while ensuring they’re within the safe corner from Ordered Fire.
Electric Excess	AoE Markers	Marks each player with circular AoE markers. Spread out to prevent overlaps.

While Sector Bisector may appear challenging, the solution is to simply find the last afterimage and move accordingly, ignoring the other images.

Boss Fight: Valia Pira

The final encounter in the Underkeep is with Valia Pira, the Indefatigable Defense:

Attack Name	Type	Details
Entropic Sphere	Roomwide AoE	Causes moderate damage to the party; be sure to use AoE heals.
Coordinate March	Cross AoEs	Two blue lines form paths with energy orbs that explode in a cross AoE upon contact. Watch the paths and move accordingly.
Turret Fire	Line AoEs	Two turrets will fire line AoEs across the room; players should position between the two active turrets to avoid damage.
Electric Field	Conal AoEs	Conal AoEs emerge from the boss; players need to move strategically to avoid overlap while accounting for the slight expansion of the AoEs.
Neutralize Front Lines/Hypercharged Light	Line AoE/AoE Markers	The boss targets a direction with a line AoE, while also marking players with circular AoEs. Move behind the boss and spread out to avoid overlaps.
Deterrent Pulse	Line Stack Marker	Targets a player with a line stack marker, prompting the group to gather and mitigate damage from the attack.

Valia Pira will continue to employ these moves until defeated. Be prepared for attacks to blend as the fight progresses—especially Coordinate March, Turret Fire, and Neutralize Front Lines. Take each attack in sequence to manage the damage effectively.

Upon taking down Valia Pira, you’ll have successfully completed the Underkeep.
