Morgeth

Overview

Morgeth, the Spirekeeper is an Ultra-ranked Taken Ogre and the third boss of the Last Wish raid. Guardians have fought larger Ogres, but he is described as the largest. Under Riven, he enforces the corruption of the Dreaming City and guards the Keep of Voices.

Encounter

Interacting with the black orbs in the arena gives a player Taken Strength. A player can hold at most two stacks, and collecting a third is fatal. More orbs spawn during the fight, and collecting them speeds up Morgeth's power build-up, which ends in a team-wipe attack. A player holding Taken Strength can be caught in a Taken curse and will die when its timer runs out. Kill the shielded Taken Knight to get the Eye of Riven, whose grenade removes the curse and frees the trapped Guardian. Using it moves the absorbed Taken Strength to the Eye holder, which can be deadly if they already hold charges.

To start the damage phase, collect the special Taken orb that spawns in the centre. Shoot the growth on Morgeth's back, since the lower its percentage, the more time the team has. During the damage phase, the Eye of Riven super resets Morgeth to 0%, which allows the team to reach a second or third damage phase.

These mechanics come from guides written around the Forsaken launch, and the encounter may have changed since then.
