Artificer Xy'mox, Healer Guide

Updated 1 month, 2 weeks ago for patch 9.2 by Preston. View the change log.

Artificer Xy'mox Dungeon Journal ModelThis page covers a healer-focused strategy for Artificer Xy'mox in Sepulcher of the First Ones in Shadowlands. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences with the encounter, combat log information, and Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Normal and Heroic

During this encounter, players will be alternating between the two stages. Stage Two occurs when Xy'mox reaches 75% and 50% health and ends when all Xy Reinforcements are killed.

Stage One - Cartel Xy

  • During Glyph of Relocation, move as far away from the affected tank as possible to reduce the damage taken.
    • This causes the tank to take light damage over time and gain Arcane Vulnerability, greatly increasing arcane damage taken.
  • When targeted by Dimensional Tear, move more than 6-yards away from other players to place the resulting wormhole in an advantageous location to help avoid other mechanics.
    • In general, one wromhole will be placed near the edge of the area and the other near the center.
  • During Forerunner Rings, use the Dimensional Tear wormholes to avoid the Genesis Rings emanating from the Genesis Relic.
    • A small ring is visible traveling up or down the Genesis Relic in the center of the room. If the ring travels from the top to bottom, it will emanate from the center of the room. If the ring travels from the bottom to top, it will emanate from the edges of the room.
  • During Hyperlight Sparknova, stay more than 3-yards away from other players to avoid chaining the damage over time effect.
  • Avoid the locations of Stasis Trap
    • Triggering a trap stuns the player and deals heavy damage over time until the Stasis Trap is killed.
    • On Heroic, Continuum Stasis Trap causes Stasis Traps to rearm after being triggered.
  • Avoid the impact locations of Gunship Barrage.

Stage Two - Secrets of the Relic

  • Xy'mox channels Decipher Relic, becoming immune to damage from Genesis Bulwark
  • The Genesis Relic deals increasing light to moderate damage to all players with Genesis Supernova.
  • Xy Reinforcements join the encounter at the start of stage two.
    • Xy Acolyte
      • Don't stand in front to avoid Massive Blast. Players hit will take increased damage from subsequent Massive Blasts.
      • At 100% Energy, becomes a Hyperlight Archon, dealing heavy damage to all players with  Hyperlight Ascension and becoming immune to crowd control effects.
    • Xy Spellslinger
      • Interrupt Debilitating Ray to prevent the moderate damage over time dealt to random players.
  • Avoid the impact locations of Gunship Barrage.

Healing Notes

Quick Notes, All Difficulties

The notes below mostly pertain to progression difficulty, meaning if you out-gear the difficulty you're on or use extra healers they may not apply.

Debuffs to Track

Major

Minor

  • Glyph of Relocation causes the tank to need light healing over time.
  • Debilitating Ray causes players to need moderate healing over time.
  • (Optional) Hyperlight Sparknova causes players to need light healing over time, however, all players will receive at least one stack sot this may clutter raid frames.
