This video is a comprehensive raid guide for the Alleria encounter in the Voidspire, covering both Normal and Heroic difficulties. It details the three phases, two intermissions, and all key mechanics, including add management, silver arrow mechanics, and boss abilities.
The fight begins with three big adds: Morium, Demiar, and Vorelus. Assign one tank to Morium, a second to Demiar, and a free tank to Vorelus after the first add dies. The raid should move together and kill one add at a time.
Each add has a special move: Morium has a tank buster called Dark Hand (big hit and knockback), Demiar has Interrupting Tremor (kicks active casts), and Vorelus has a 15-yard AOE to avoid.
Adds are immune to death until hit with a Silverstrike Arrow, which breaks their umbral tether. The arrows target players with straight-line attacks, and the add highlights when aimed correctly. Hit each big add with one arrow.
Void droplets should be brought on top of the add being fought, as their splashes increase damage taken. Players who accidentally pick up Corrupting Essence stacks can have it dispelled by healers.
Grasp of Emptiness is a projectile attack linked to a player; the linked player can aim the projectiles away from others. Void Expulsion is an AOE to dodge that leaves puddles—do not stand in them.
Null Corona is a massive heal absorb that goes on a couple of people and needs to be healed off. Do not dispel it, as the remaining absorb jumps to someone else.
The boss is immune during the first intermission. Avoid getting sucked into the middle and dodge silver arrows fired from the center. Standing in one arrow can reset the suck-in if struggling.
Alleria summons a Rift Simulacrum, which should be tanked at least 25 yards away. It's a split cleave situation; DoT both if possible. Tank swap around three stacks of the debuff.
Undying Voidspawn adds cast Void Barrage, which should be interrupted. They need to be hit with bouncing silver arrows to die. Do not aim at the Simulacrum with these arrows.
Volatile fissures are bright blue floor sections that burn. Avoid crossing them unless necessary. The second intermission is like the first but with extra orbs to dodge.
Fight on a third of the floor at a time and escape to clean floor when it fills with void. Aspect of the End tethers three players to an arrow; get 30 yards away to snap the tether.
To jump to another part of the room, run into a feather, ensure you have the buff, and actively jump over the edge. The buff is mandatory.
On Heroic, more puddles spawn, filling the floor faster. Silver arrows in intermissions debuff you for 8 seconds, making a second arrow within that window extremely deadly.
The guide provides a complete breakdown of the Alleria encounter, emphasizing the importance of silver arrow mechanics, add control, and positioning. Mastery of the intermission and phase transitions is key to success on both difficulties.

04:57[00:00] Hi! I’m Hazel, and this is a guide to the Alleria fight in the Voidspire on Normal and Heroic difficulty. This is our final boss of the Voidspire, so it’s only right that we’ve got three phases and two intermissions to deal with.
[00:14] We start out fighting Three big adds. They will stick near their spots, so Put one tank on Morium, send the second to Demiar and move a free tank to Vorelus
[00:28] as soon as the first add dies. The raid can move together and kill one add at a time. Each of these adds has one special move. Morium’s is a tank buster called Dark Hand. That does a big hit and a knockback, so watch the edge if you’re tanking.
[00:43] Demiar does Interrupting Tremor, which will kick any active casts when it finishes. And then Vorelus has a 15 yard AOE, just get out.
[00:55] So the catch here is each add starts out immune to death. We gotta Hit the add with a Silverstrike Arrow to break it’s umbral tether and allow it to be killed. The silver arrows target a few
[01:07] players with straight line attacks, and the add c will actually highlight when you’re aiming at it correctly. It doesn’t matter if you’re in front of or behind it as long as it’s in the path of your arrow. Hit each big add with one of those, and otherwise just avoid hitting friends.
[01:22] Meanwhile, We’ve also got goopy little void droplets. Bring those on top of the add that you’re fighting. The splashes they do will increase damage taken by anything they touch, so stacking them on the add helps us kill it faster. If
[01:35] any players do accidentally pick up stacks of Corrupting Essence, healers can dispel it off. Grasp of Emptiness is a projectile attack that gets linked to a player. Both the circle and projectiles do damage. What makes this cool is The linked
[01:50] player can move to aim the projectiles. It’s A bit like drawing a weapon. Point those as best as you can away from people, and everyone else can dodge. Void Expulsion is an AOE to Dodge that leaves puddles. It looks a little bit like a soak,
[02:05] but it is not, do not stand in this. These spawn near ranged, so if your floor is a mess you can try baiting them out of the way. Null Corona is a massive heal absorb you’ll see throughout the fight. It’ll go onto a couple
[02:19] people and just needs to be healed off. If it is dispelled, the remaining absorb jumps to someone else so just leave it be and heal it unless the target is in grave danger. Once our three big boys have died, it’s time for the first intermission. Don’t
[02:35] bother hitting the boss, she’s immune. Your job is to not get sucked into the middle. Silver arrows will fire out from the center- avoid those. If you are really struggling with how strong the suck-in is, you can stand in one arrow to reset it.
[02:51] After that’s done, it’s time for Phase Two. Alleria will summon a Rift Simulacrum, Tank that at least 25 yards away from her. her simulacrum. This is a split cleave situation- if you can DoT both, do it.
[03:09] stacking up a debuff. Tank swap around three stacks. damage while the shield lasts. Damage off this shield to give your healers a break.
[03:24] Undying Voidspawn adds will try to cast- Interrupt their Void Barrage to group them up and cleave them down. In order for them to die, we need to hit them with more silver arrows - this time,
[03:37] fancy ones that bounce between players. Take a look at the graphic and Try to line up the silver path over Voidspawn adds so they can die. Do Not aim at the Simulacrum, it won’t do anything.
[03:50] Volatile fissure will burn if you if you step on these bright blue bits of floor. Don’t cross floor sections until if you have to, and don’t loiter on the gaps. When the Simulacrum dies, we get another intermission. This is just like the first one,
[04:05] but with some extra orbs to dodge. Fight the pull, live and it’s time for phase three. This kinda like Sylvanas. We fight her on a third of the floor at a time, and have to escape to clean floor when she fills it up with void..
[04:19] Aspect of the End Tethers three players to an arrow, get 30 yards away to snap your tether. The first break should go ASAP, then stagger out the others a little to let the healers catch up.
[04:32] There are still absorbs to heal and void arrows to aim. When it’s time to jump ship to another part of the room, run into a feather, make sure
[04:44] you got the buff, then jump over the edge. You must have the buff, and you must actively jump. On Normal, that’s it! On Heroic, we’ve got a couple of changes.
[04:57] There’ll be more puddles spawning, so the floor will fill faster. The silver arrows in the intermissions now debuff you for 8 seconds, making you take WAY more damage from a second one. If you take two arrows within 8 seconds
[05:11] during the heroic intermissions, you are most likely extremely dead. And that’s it, at least in the dungeon journal. If there’s any surprises, please help your fellow raiders out and drop in the comments. Thanks for watching,
[05:24] I’ve got more raid guides if you want ‘em and have a wonderful, wonderful day. Bye!
