“

An extensive warren of tunnels and waterways stretches beneath the barren lands of Thanalan, but none come now to marvel at this remnant of fallen Sil'dih. Its memories lie undisturbed, festering silently in the dark and the damp. Yet not for much longer. You have come at the personal behest of Nanamo Ul Namo, and together will you throw open the gate to the desert nation's troubled past.

Bosses

Geryon the Steer

First boss of all paths.

• Colossal Strike: Tankbuster.
• Explosive Catapult: Light damage to the entire party and summons several explosive barrels with either a red "burst" design on its top, or a blue "ring" design. The red-topped barrels explode in a large circle around them, while the blue-topped ones explode in a large ring around them.
• Colossal Slam: Cone attack in the direction of a random player.
• Subterranean Shudder: Has various effects depending on which path the party has taken and what decision was made before encountering Geryon.
  • Left Path: There will be four drains on both the east and west sides of the arena. The choice of whether or not to clear the pipes affects the attack.
    • Cleared Drain: One of the drains will light up cyan, causing water to spill out and knock back players from its location.
    • Clogged Drain: Two to four of the drains will light up red, causing mud to spill out and form damaging puddles on the ground for a short duration.
  • Center Path: The direction the Bulkhead Handle is turned determines the effect of the attack.
    • Turn Left: To the east and west of the arena are vents with fans. One set will begin to spin, indicating that players will be dragged across the arena toward that side.
    • Turn Right: To the east and west of the arena are platforms. Boulders will be carried onto them, then roll across the arena in a straight line during the next Explosive Catapult cast, dealing massive damage to players they crush.
  • Right Path: Mechanic is based on what fluid bursts from the pipe prior to the boss and is completely random.
    • Water: Two opposite quadrants of the arena churn, followed by the other two. The quadrants explode for damage in the order they began churning.
    • Ceruleum: Two adjacent quadrants of the arena explode, dealing damage and creating a puddle on them that deals damage over time.
• Colossal Launch: Geryon slams the ground, dealing light damage to the party and causing all explosive barrels to flip over, turning red to blue and vice versa.
• Colossal Swing: Geryon jumps to the center of the arena and swings in a 180 degree arc in a random cardinal direction.
• Colossal Charge: Geryon jumps to the north or south of the arena and creates an energy shield that he angles to the east or west. He then charges across the arena in a line, knocking back players and barrels in his path to the indicated direction. A barrel pushed by this attack will have its explosion radius overlap with the safe area of any blue barrels on that side.
• Gigantomill: Geryon moves to the center of the arena and launches multiple cross AoEs while rotating clockwise or counterclockwise.

Soapy Sidekick: Silkie

Second boss of the left path.

Lifeless Legacy: Gladiator of Sil'dih

Second boss of the middle path.

Undead Shadowcaster: Zeless Gah

Second boss of the right path.

Armed Automaton: Thorne Knight

Secret second boss of the right path.
