Rygelon, Healer Guide

Updated 1 year, 2 months ago for patch 9.2.7 by Preston. View the change log.

Rygelon Dungeon Journal ModelThis page covers a healer-focused strategy for Rygelon 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

  • The tanks will be dealing with Corrupted Strikes, which requires use of active mitigation to avoid gaining excessive stacks of Corrupted Wound.
  • Unstable Matter spheres appear near pylons on the edges of the room.
  • During Celestial Collapse, six Collapsing Quasars spawn on the six anima-infused patches circling the center of the room.
    • Collapsing Quasar
      • Attempts to reach Rygelon, increasing its damage dealt and dealing stacking light damage over time to all players with Quasar Radiation.
      • Upon death, leaves behind a Collapsing Quasar Field.
        • This is used to deal with Dark Eclipse, detailed below.
        • After entering the field, stay more than 5-yards away from other players to avoid chaining the damage from Event Horizon.
      • On Heroic, gradually gains stacks of Accretion, increasing movement speed and reducing effectiveness of slow effects.
  • On Heroic, during Manifest Cosmos, one Cosmic Core spawns.
    • Cosmic Core
      • Targets the nearest player with Cosmic Ejection, dealing stacking moderate to heavy damage over time to all players within 5-yards.
  • When affected by Dark Eclipse:
  • During Massive Bang, run against the pull to remain inside an Unstable Matter Field to enter The Singularity.
    • While inside The Singularity:
      • Deals increasing light to moderate damage over time to all players with Eternal Radiation.
      • Shatter Sphere triggers Unstable Antimatter, removing all players from The Singularity while dealing stacking light damage over time.
        • On Heroic, this deals fatal damage to all players if a Cosmic Core is still alive.
      • On Heroic, Cosmic Cores are present from outside The Singularity.
        • Cosmic Core
          • Players must stand within 5-yards to be damaged by Stellar Decay, which in turn damages the Core.
          • Upon death, a tank must stand within 8-yards to take the heavy damage and heavy damage over time from Gravitational Collapse.
            • If no player is hit, the effect instead hits all players.
  • Avoid the lines of Celestial Terminator.
  • If no players are available to be targeted, Radiant Plasma deals moderate damage over time to all players until a target is available.

Mythic Differences

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

  • Corrupted Wound causes the tanks to need light to moderate healing over time.
  • Gravitational Collapse causes the tanks to need heavy healing over time.
  • Dark Eclipse causes players to need light healing over time, and will deal moderate damage to all players if the affected player dies.

Minor
