General Information

On this page, we list all the abilities from the Portal Keeper Hasabel encounter in Antorus, the Burning Throne. The idea is to give you a solid understanding of the encounter before you read the strategy.

If you are already familiar with the encounter, then you can skip to the strategy and tactics page or access any other page of the guide by using the table of contents on the right.

Portal Keeper Hasabel is a unique encounter, featuring a main boss and 3 mini-bosses. Each enemy occupies their own platform, which can only be accessed by the portals that Hasabel herself opens. There are plenty of adds throughout the fight, pouring through the portals to engage the raid. Hasabel requires significant coordination on higher difficulties, but she will always test the groups damage and teamwork.

Portal Keeper Hasabel is technically a single-phase fight, and she will use the same abilities throughout the encounter. At certain health values, however, she will open specific portals that access the mini-bosses and allow new adds to join the encounter. This splits the fight into four pseudo-phases that each have a distinct theme.

The main platform has three portals that can be entered at any point during the encounter. There is a red portal, a green portal, and a purple portal, and each takes you to a corresponding platform. Although the portals can be accessed at any point during the encounter, there is little incentive to do so until the boss "activates" them, which occurs during set health breakpoints in the encounter (90%, 60%, 30%). When this happens, a mini-boss will spawn on its respective platform and members of the raid will travel through the portal to engage and defeat it.

There are specific situations where it may be valuable to enter a portal even though there is currently no mini-boss to defeat. These moments are addressed on our Strategy page.

Portal Keeper Hasabel occupies the main platform where the raid enters, which is designated "Platform: Nexus" in the dungeon journal. Hasabel will never leave Platform: Nexus.

Reality Tear is a stacking Tank debuff which inflicts Physical damage every 2 seconds for 30 seconds. When the debuff expires, it inflicts Shadow damage to all players in the raid based on the number of stacks.

Collapsing World opens a portal at Portal Keeper Hasabel's current location. A large circle with a 30 yard radius will appear, and the raid will have several seconds to escape the blast radius. Players still inside the radius of the Collapsing World portal will suffer heavy Shadow damage and be knocked away. All players will receive moderate Shadow damage, regardless of positioning.

Felstorm Barrage opens a portal that spews a barrage of fel fireballs that rain down in a line. Anyone struck will suffer heavy Fire damage and be knocked back. Felstorm Barrage manifests as massive green lines on the ground, covering the entire length of the platform and roughly 10 yards wide. They appear as a visual for a few seconds before the actual barrage lands, giving you time to move.

Transport Portals appear periodically and summon demons to assist Hasabel throughout the fight. The portals remain open for 10 seconds before disappearing.

Felblaze Imps will begin to appear once the portal to Xoroth has been opened. They cast Fiery Detonation, which kills the imp but inflicts moderate raid-wide Fire damage, as well as increasing damage taken from any subsequent Fiery Detonations by 50% for 6 seconds. This cast is interruptible.

Feltouched Skitterers will begin to appear once the portal to Rancora has been opened. They cast Acidic Web at random players, immobilizing them for 5 seconds and dealing ticking Nature damage.

Hungering Stalkers will begin to appear once the portal to Nathreza has been opened. They cast Howling Shadows, which deals moderate Shadow damage and interrupts spellcasting for 6 seconds. This cast is interruptible.

Catastrophic Implosion is only cast if no players are currently on Platform: Nexus. It deals heavy raid-wide Fire damage that stacks a buff on Hasabel and her allies, increasing cast speed(s) by 100% and damage done by 25% by 12 seconds.

A portal to "Platform: Xoroth" opens when Portal Keeper Hasabel reaches 90% health. A mini-boss named Vulcanar will arrive through the portal, empowering it until he is defeated by the raid. Players can access "Platform: Xoroth" using the red portal on "Platform: Nexus".

While Vulcanar is alive, the portal will deal Fire damage every 2 seconds to players on Platform: Nexus via Empowered Portal: Xoroth. The ticking damage increases by 3% every 3 seconds.

After Vulcanar has been defeated, the raid will continue to suffer Fire damage via Portal: Xoroth. The damage now ticks every 4 seconds, is significantly lessened, and does not increase in intensity over time. This ticking damage persists until the end of the encounter.

Flames of Xoroth deals moderate Fire damage to all players within 10 yards, and applies a debuff that deals ticking Fire damage for 5 seconds.

Supernova marks a 6 yard circle on the floor, which explodes after several seconds. Anyone caught within the zone suffers very heavy Fire damage and is knocked in the air.

Unstable Portal is cast 45 seconds after arriving, and at periodic intervals thereafter. It deals heavy raid wide Fire damage, and buffs the caster by increasing all cast speeds by 20% and all damage done by 25% per stack. The buff lasts 12 seconds, and the cast is interruptible.

Everburning Flames manifest as orbs of flame. There are four Everburning Flames at the back of the platform. Coming into contact with one causes the player to receive moderate ticking Fire damage every 2 seconds for 10 seconds. When the debuff expires, it falls back to the ground as a flaming orb and provide nearby players with Everburning Light.

Players within 10 yards of Everburning Flames are buffed with Everburning Light, which protects them from Mind Fog (explained under the "Platform: Nathreza" section).

A portal to "Platform: Rancora" opens when Portal Keeper Hasabel reaches 60% health. A mini-boss named Lady Dacidion will arrive through the portal, empowering it until she is defeated by the raid. Players can access "Platform: Rancora" using the green portal on "Platform: Nexus".

While Lady Dacidion is alive, the portal will deal Nature damage every 2 seconds to players on Platform: Nexus via Empowered Portal: Rancora. The ticking damage increases by 10% every 3 seconds.

After Lady Dacidion has been defeated, the raid will continue to suffer Nature damage via Portal: Rancora. The damage now ticks every 4 seconds, is significantly lessened, and does not increase in intensity over time. This ticking damage persists until the end of the encounter.

Felsilk Wrap webs a player completely, stunning them until the webbing can be destroyed. The webs have a health bar and can be attacked by allies. The Felsilk Wrap deals ticking Nature damage every second until it is destroyed.

Poison Essence occurs periodically to players within 70 yards of "Platform: Rancora", dealing 10% of their current health as Nature damage.

Unstable Portal is cast 45 seconds after arriving, and at periodic intervals thereafter. It deals heavy raid wide Fire damage, and buffs the caster by increasing all cast speeds by 20% and all damage done by 25% per stack. The buff lasts 12 seconds, and the cast is interruptible.

Touching any of the fel pools on "Platform: Rancora" applies Caustic Slime, which deals ticking Nature damage every 2 seconds. When removed, it triggers a Caustic Detonation. There are four Caustic Slimes, located at the rear of the platform.

Caustic Detonations inflict moderate Nature damage to any players within 10 yards, and remove a stack of Aegis of Flames (a Mythic-only mechanic).

A portal to "Platform: Nathreza" opens when Portal Keeper Hasabel reaches 30% health. A mini-boss named Lord Eilgar will arrive through the portal, empowering it until he is defeated by the raid. Players can access "Platform: Nathreza" using the purple portal on "Platform: Nexus".

While Lord Eilgar is alive, the portal will deal Shadow damage every 3 seconds to players on Platform: Nexus, as well as reducing damage done by 1% for 4 seconds, via Empowered Portal: Nathreza. This effect increases by 10% every 3 seconds.

After Lord Eilgar has been defeated, the raid will continue to suffer Shadow damage via Portal: Nathreza. The damage ticks every 3 seconds, is significantly lessened, and does not increase in intensity over time. This ticking damage persists until the end of the encounter.

Delusions affects all Healers within 35 yards, reducing healing and absorbs by 100%. 2% of maximum Mana is restored every 1 second during this time. It lasts for 10 minutes or until you are out of range.

Corrupt affects players within 20 yards, inflicting moderate Shadow damage and increasing all damage they suffer by 15% for 4 seconds, per stack.

Unstable Portal is cast 45 seconds after arriving, and at periodic intervals thereafter. It deals heavy raid wide Fire damage, and buffs the caster by increasing all cast speeds by 20% and all damage done by 25% per stack. The buff lasts 12 seconds, and the cast is interruptible.

Mind Fog reduces view distance significantly, and prevents the targeting of enemies. Mind Fog only affects players on Platform: Nathreza. Players affected by the Everburning Light buff are unaffected by Mind Fog. In order to be affected by Everburning Light, a player will have to enter the red portal, carry one of the Everburning Flames back through to the main platform and through the purple portal.

Cloying Shadows affects players on Platform: Nathreza, reducing all healing received by 50% for 30 seconds. Upon expiration it triggers Hungering Gloom.

Hungering Gloom inflicts moderate Shadow damage to all players within 8 yards. Additionally, all healing received is reduced by 100% for 60 seconds.
