Immediately following the foundation of the Astral Ward, Eparch finally returned to Tyria to strike back against Isgarren's "betrayal"—this time with a full entourage. Help Isgarren, Mabon, and Dagda navigate the crumbling halls of the Wizard's Tower and push the Kryptis back to where they came from.

Upon entering the fractal take the Mistlock Singularity and head out the starting room and follow the corridor to your right. Whilst moving down the corridor avoid Cerus's Despair attack (the falling red orbs, leaving AoEs on the ground), standing in this attack will apply Agony and 5 stacks of Torment. At the end of the corridor you will see Cerus standing in the Astral Purifier room.

Once you have completed the Astral Purifier event, you can /gg to respawn in the starting room. Leave the starting room, once again taking the Mistlock Singularity if availible. However, this time turn left and move down the corridor. This time as well as Cerus's Despair attack (the falling red orbs) from before, you will also have to deal with Deimos's Grasping Hands, that apply Poisoned, Torment, and Crippled. At the end of the corridor you will come to a single Astral Purifier node, which requires you to play the same minigame as before. Repairing this node will allow access to the room with the brothers Cerus and Deimos standing in. Both bosses will fixate and move towards the closest player to them, with the players gaining the Cerus's Focus and Deimos's Focus effects respectively. When the brothers are close together they will gain the effect Brothers United leading their attacks to deal more damage.

Once you have defeated the brothers, take the portal to the final boss. Before fighting Eparch, you will have to kill some trash mobs. Once you have dealt with them you can /gg again, to reset cooldowns and prestack boons while Eparch spawns. When ready aproach the white circle on the ground to enter the arena.

As Eparch carries out each attack, he will spawn Globules of Emotion. These can be collected by players giving different effects, some positive and some negative. Each attack has a corresponding emotion that it will spawn which can be seen in the table below. If you have stacks of a Globule of Emotion and go to collect a different type, each new Globule will remove a stack of the previous effect until you start to gain stacks of the new effect.

With this in mind, it makes sense for the following roles to prioritise the following Globules of Emotion to maximise party damage:

With Challenege mode enabled, the majority of the fractal plays out the same as the T4 version. The main difference is the Eparch encounter which gains the following changes:

The rest of the encounter is exactly the same as the T4 mode.

When reaching a split phase, Eparch will leave the Arena and spawn 2 rifts in the 65% phase, and 3 rifts in the 35% phase. Each rift will spawn a Champion incarnation of Judgement, or a Champion Incarnation of Cruelty, along with some trash mobs. To close the rift, its associated Champion must be killed, to allow players to close the rift by channeling in a white AoE that spawns. Meanwhile the mobs will be drawn towards Eparch, who is floating above the arena. When the adds get close, they tether to Eparch giving him stacks of Globules of Emotion.
