The Navel (Extreme)

To unlock the trial, player must be on the quest Quake Me Up Before You O'Ghomoro and should have completed Galeforce Warning and defeated Garuda (Extreme).

Strategy:

• Everyone who is not tanking should stack up directly behind Titan. This includes the healers and ranged classes.
  Titan will target two players with Gaol. He preferentially targets one DPS and one Healer. When targeted by Gaol, DPS should stand directly under Titan. The healer needs to run to the far edge. If there is a yellow line connecting the two players, you're too close together.
  

Phase 1: Before the Jump
Very straightforward, tank Titan on the edge of the room and avoid his Landslides and Weight of the Land. At the end of this phase, Titan will jump in the air to knock away the edges of the arena.

• Rotation: Landslide; Weight of the Land; 4 Tumults, with Mountain Busters every so often
  Tanks: switch off every 2-3 stacks of Mountain Buster
  

Phase 2
This works much like Phase 1, with some interesting differences. Landslide now goes in three directions. Titan starts using Gaol and Bomb Boulders.

• When targeted by Gaol, DPS should stand directly under Titan. The healer needs to run to the far edge. Free the DPS first, then free the healer.
  The first set of Bomb Boulders will be a pattern that covers 2/3 of the arena. You must move to the safe spot to avoid them.
  Further Bomb Boulders will be in a circle. Wait for the first bombs to explode, then move into their area to avoid the second bombs' explosions.
  

Rotation: Geocrush -> Landslide -> Gaol x2 -> Mountain Buster -> Upheaval -> Landslide -> Stomps x4 -> Weight of the Land -> Mountain Buster -> Landslide -> Weight of the Land -> Bombs -> Mountain Buster -> Landslide -> Gaol x2 -> Repeat

Phase 3: Heart
This phase starts when Titan reaches 55% health. Target Titan's Heart. As before, dodge Landslides (which now go five ways) and Weight of the Land, and deal with Gaols. Titan will also drop Bomb Boulders in circles. Wait for the first bombs to explode, then move into their area to avoid the second bombs' explosions.
You have until the third Weight of the Land to destroy the heart, or you will wipe.

Rotation: Geocrush -> Weight of the Land -> Gaol x2 -> Upheaval -> Landslide -> Stomps x4 -> Weight of the Land -> MB -> Clockwork Bomb -> Landslide -> Stomps x4 -> Weight of the Land -> Earthen Fury (failure)
