Artificer Xy'mox is a three phase encounter in which the raid needs to place two wormholes in the boss room. Players who run into one wormhole will instantly teleport to the other, allowing the raid to deal with the bosses deadly abilities! The boss keeps one set of abilities throughout all phases, aside from one main "relic" ability which changes each phase.

Artificer Xy'mox is unlocked by defeating Shriekwing, the first boss in Castle Nathria. Killing Artificer Xy'mox along with Sun King's Salvation unlocks The Council of Blood. 

Artificer Xy'mox Quick Tips in Castle Nathria

• Players marked with Dimensional Tear will need to place the wormhole spawned by the debuff in specific locations depending on what relic is active!

• You can instantly teleport between the two wormhole locations by moving into one of them.

• Tanks need to take turns taking the Glyph of Destruction. Use the wormhole or run far way when it is applied to you!

• Dodge the line attacks from the portals when the boss casts Rift Blast.

• Hyperlight Spark deals high unavoidable raid damage to each member of the raid... heal them up!

The three phases are defined by three Relics placed by Artificer Xy'mox. These change based on the boss's health:

Relic 1: Crystal of Phantasms - 100% - 70% Health

• Place the Dimensional Tear wormholes in the far east and far west. The raid should be positioned around one of these wormholes.

• Kite your add whilst utilizing the wormholes if you are fixated by a Fleeting Spirit to avoid being mind controlled!

• Damage any players who become mind controlled to free them.

Relic 2: Root of Extinction - 70% - 40% Health

• Place the Dimensional Tear wormholes in the far east and far west. The raid should be positioned around one of these wormholes.

• Have one player pick up the nearby Seed of Extinction and use the wormhole to move it far away from the raid.

• Have one player pick up the seed at the north of the room and another to the south. They should move the seeds far away and use the wormhole to return.

• Spot heal any player afflicted with Witheri Withering Touch!

Relic 3: Edge of Annihilation - 40% - 0% Health

• Place the Dimensional Tear wormholes in the middle of the room and against the west/east wall of the room.

• Run into the wormhole in the middle of the room just before the Edge of Annihilation cast completes as to avoid the 25 yard radius lethal damage.

• Try to remain relatively stacked as to allow healers to counter the constant Aura of Dread damage.
