This page covers a healer-focused strategy for Portal Keeper Hasabel in Antorus, the Burning Throne. 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 fight as well as Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Normal and Heroic

During this fight, Hasabel will be opening various portals to unleash different Legion forces.

Platform: Nexus

This is the base platform which all of the portals connect to.

• The tanks will be managing stacks of Reality Tear.
  • Upon expiring, Bursting Darkness deals damage to the group based on the number of stacks.
• Move out of Collapsing World to avoid fatal damage.
  
  • This deals light damage to the entire group, even outside of the affected area.
• Avoid the lines created by Felstorm Barrage.
• If no players are on the Nexus Platform, Catastrophic Implosion occurs.
• On Heroic, Transport Portal summons various demons to the fight.
  • Felblaze Imp
    • Fiery Detonation needs to be interrupted or subsequent casts will deal increasing damage to the group.
  • Feltouched Skitterer
    • Acidic Web roots players and deals light damage over time.
  • Hungering Stalker
    • Howling Shadows needs to be interrupted or spell casts should be stopped before it finishes casting.

Platform: Xoroth

When Portal Keeper Hasabel reaches 90% health, she opens the portal to Xoroth. Players must enter the portal to kill Vulcanar.

• Vulcanar
  • Stay at least 10-yards away from Vulcanar to avoid Flames of Xoroth.
    • Ideally, this will be interrupted every time to avoid heavy damage on the tank and melee.
  • Avoid the impact locations of Supernova
• Empowered Portal: Xoroth deals steadily increasing damage to the group while Vulcanar is alive.
  • Once Vulcanar is killed, Portal: Xoroth continues to deal light damage to the entire group.
• When affected by Everburning Flames, move away from the group to drop the resulting Everburning Light.
  • One player must take the flames back through the portal to the Nexus Platform. 
  • Standing near Everburning Light will remove Mind Fog from the Nathreza portal.

Platform: Rancora

When Portal Keeper Hasabel reaches 60% health, she opens the portal to Rancora. Players must enter the portal to kill Lady Dacidion.

• Lady Dacidion
  • Destroy the Felsilk Wraps on affected players to remove the stun.
  • Poison Essence deals damage to all players based on their current health amount.
• Avoid the Caustic Slime pools.
  • Before the debuff expires, move at least 10-yards away from other players to avoid causing extra damage from Caustic Detonation.
• Empowered Portal: Rancora deals steadily increasing damage to the group while Lady Dacidion is alive.
  • Once Lady Dacidion is killed, Portal: Rancora continues to deal light damage to the entire group.

Platform: Nathreza

When Portal Keeper Hasabel reaches 30% health, she opens the portal to Nathreza. Players must enter the portal to kill Lord Eilgar.

• Lord Eilgar
  • Periodically applies Delusions to healers within 35-yards.
    • This effect can be dispelled and should be used to regain mana as needed.
  • If possible, stay at least 20-yards away to avoid Corrupt.
• Empowered Portal: Nathreza deals steadily increasing damage to the group while Lord Eilgar is alive.
  • Once Lord Eilgar is killed, Portal: Nathreza continues to deal light damage to the entire group.
• Mind Fog reduces how far players can see.
  
  • Standing near an Everburning Light from the Xoroth portal removes the effects of Mind Fog.
    • It's possible to have all players stack on the boss to negate the need for Everburning Light, which is most viable in Normal and Heroic.
  • When affected by Cloying Shadows, move at least 8-yards away from other players to avoid spreading it.

Mythic Differences

Platform: Nexus

• Transport Portal
  • All adds periodically increase their damage done and movement speed with Unrelenting.

Platform: Xoroth

• Vulcanar
  • The three stacks of Aegis of Flames reduces damage taken.
    • The stacks must be removed with a Caustic Detonation from the Rancora portal. Each Caustic Detonation removes one stack.

Platform: Rancora

• Lady Dacidion
  • Poison Essence is now Leech Essence and heals Lady Dacidion for five times the amount of damage dealt to the five nearest players.
    • This is countered by Hungering Gloom from the Nathreza portal. You will likely need two to three Hungering Gloom before Dacidion is killed.

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.

• Use Major Cooldowns on
  • Collapsing World during Empowered Portal: Xoroth, Empowered Portal: Rancora, or Empowered Portal: Nathreza, which occur when their respective portals are active and deal increasing damage over time to players inside the active portal.
  • The final moments of the fight, when all portals are closed and the group is taking damage from all of them at once.
• Use Minor Cooldowns on
  • Collapsing World during Empowered Portal: Xoroth, Empowered Portal: Rancora, or Empowered Portal: Nathreza, if major cooldowns aren't available or aren't necessary.
  • The final moments of the fight, when all portals are closed.
• Pre-heal Before (mainly for heal over time classes)
  • Collapsing World
  • Entering an Empowered Portal
• Leytorrent Potion use
  • After Felstorm Barrage, ideally when an Empowered Portal isn't active.
• Other things to watch for
  • Dispell Delusions from yourself once you've gained enough mana or if you need to continue healing.
  • Cloying Shadows and Hungering Gloom can be dispelled once the affected player is away from the group.

Debuffs to Track

• Cloying Shadows can be dispelled once the affected player is away from the group.
• Hungering Gloom can also be dispelled once the affected player is away from the group.
• Delusions can be dispelled as needed.
• (Optional) Several abilities deal light damage over time.
  • Everburning Flames, this can also be dispelled if needed.
  • Caustic Slime
  • On Heroic, Acidic Web
