Terros, Healer Guide

Updated 2 weeks, 5 days ago for patch 10.0 by Preston. View the change log.

Terros Dungeon Journal ModelThis page covers a healer-focused strategy for Terros in Vault of the Incarnates in Dragonflight. 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.

Terros ModelGeneral Mechanics and Abilities

Terros ModelNormal and Heroic

  • The tanks will be dealing with Concussive Slam, a targeted line used to destroy Awakened Earth pillars, detailed below.
    • This applies a stack of Concussive Slam to all players hit, and will eventually require a tank switch.
  • Every 40-seconds, during Rock Blast:
    • Move within 12-yards of the player targeted by Rock Blast to split the damage dealt.
      • Avoid the Aftershock left behind. Players hit take moderate damage and are knocked into the air.
    • Several players are targeted by Awakened Earth pillars:
      • When targeted, stay more than 2-yards away from other players to avoid chaining the damage dealt. Ideally, move to one side of the Rock Blast.
      • Each Awakened Earth pillar deals light damage over time to all players until destroyed with Concussive Slam, detailed above.
        • When destroyed, deals light damage to all players with Seismic Assault and applies a stack of Seismic Assault to all players, dealing additional light to moderate damage over time.
  • Avoid the impact location of Shattering Impact targeted at a tank's location.
  • At 100% Energy, about every 90-seconds, during Resonating Annihilation:
  • Shortly after the fourth Resonating Annihilation, about 6-minutes into the encounter, Frenzied Devastation deals increasing moderate to heavy damage over time to all players for the rest of the encounter.
  • If no players are in melee range, Tectonic Barrage deals heavy damage over time to all players.

Terros ModelMythic Differences

  • Rock Blast now also deals moderate damage to all players outside the effect.
  • About every 25-seconds, delayed by most other abilities, applies Infused Fallout to all players, dealing light damage over time until the effect is cleared.
    • Touching another affected player deals light damage to all players with Explosive Reaction and removes the effect from both players.


Terros ModelHealing 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.

  • Use Major Cooldowns
  • Use Minor Cooldowns on
  • Pre-heal Before (mainly for heal over time classes)
    • Rock Blast
    • or, keep heal over time effects active due to persistent damage throughout the encounter
  • Potion of Frozen Focus use
  • Other things to watch for
    • Healing required stays relatively high through out the encounter, but ideally it won't last longer than 6-minutes.
