Introduction
Welcome to our Mythic Imperator Averzian Boss Guide, for The Voidspire Raid. Learn about the Mythic specific fight mechanics and the strategy we recommend to defeat this boss on Mythic difficulty!
This guide focuses on a Mythic strategy, and won’t explain the basics of the fight, so make sure you read through the Heroic version of the guide for this boss if you are unfamiliar with the encounter.
Fight Style: Single Target fight with burst AoE moments
Recommended Setup: 2x Tank / 4x Healer / 14x DPS
Required utilities: Dispels
Hero/Lust usage: On Pull
Addons: Northern Sky Raid Tools
Easy Mode
General:
- Same fight as Heroic, still a tic tac toe boss. Do not let the boss get three claimed tiles in a straight line.
- Mythic mostly adds dispel work and one extra annoying add.
Cosmic Shell and Void Marked:
- Every Abyssal Voidshaper has Cosmic Shell with 2 stacks.
- While shielded, they are immune to damage and Umbral Collapse.
- Random players get Void Marked.
- Move Void Marked players onto the Voidshaper marker your raid lead calls, then dispel them there.
- Each dispel removes 1 stack of Cosmic Shell, so you need 2 dispels per Voidshaper to break it.
- Once the shell is gone, you handle it like Heroic.
Add Priorities:
- The Voidshaper you end up fighting is kill priority, its energy ramps fast and 100 energy is usually a wipe.
- Abyssal Malus is new:
- Interrupt Pitch Bulwark.
- Interrupt Black Miasma or several players get 70% haste reduction for 15 seconds.
Voidmaws:
- At 35% HP, Voidmaws walk toward a claimed spot.
- If they reach it, they heal back to full.
- Don’t tank them right next to claimed tiles.
Rest of the fight:
- Dodge the usual stuff, follow the board calls, handle dispels cleanly, and the boss dies.
Mechanics
Each Abyssal Voidshaper starts protected by Cosmic Shell, making it immune to damage and also immune to Umbral Collapse.
To remove the shell, you need Void Marked dispels on top of that Voidshaper. It takes two dispels to break the shell. Once Cosmic Shell is gone, you can handle that Voidshaper normally again.
Deals ticking damage to the player and fades after 10 seconds.
This debuff is dispellable, and it’s essential on Mythic. If you get Void Marked, move on top of the Abyssal Voidshaper you want to remove the shell from and call for a dispel.
Two players need to be dispelled on the same Voidshaper to destroy Cosmic Shell, and then you proceed like on Heroic.
Abyssal Malus
New add type.
It still has Pitch Bulwark, placing a large absorb shield like on Heroic, so you still want to interrupt that.
It also casts Black Miasma, which reduces several players’ haste by 70% for 15 seconds if not interrupted.
Strategy
Here’s the map layout:
Traditionally, first bosses on Mythic don’t suddenly turn into a completely different game compared to Heroic, and this boss is no exception. You’re doing the same movements, the same positioning, the same “don’t let him get three in a line” tic tac toe plan, and the same general add handling.
The Mythic changes basically add just enough extra work to punish sloppy play, and that’s about it. The fight is still decided by whether your raid lead calls the right tiles, and whether people actually do what they’re told.
The tic tac toe rule still decides the pull
Shadow's Advance still spawns three Abyssal Voidshapers on the board. If too many tiles get claimed and the boss can connect three in a straight line, you trigger the “you lost” situation and the pull ends.
So your raid leader’s job is still the same as Heroic:
- Choose which two tiles get saved each wave.
- Avoid setting up a future three-in-a-row.
- Keep the center and diagonals in mind, because those are where people grief themselves without noticing.
- Be aware when the pattern requires big movement from a corner to the opposite corner. Dispel and soak one of them, then gateway + movement speed to the far one and dispel quickly to soak.
Everything below is just extra steps on top of that same board game.
Void Marked and Cosmic Shell
On Mythic, each Abyssal Voidshaper is protected by Cosmic Shell, which makes it immune to damage and also immune to Umbral Collapse. Each shell has two stacks, so you can’t just “solve” the wave with collapse circles anymore.
To remove Cosmic Shell, you use Void Marked.
Random players get Void Marked. It deals ticking damage and lasts 10 seconds, but it can be dispelled. When you dispel Void Marked on top of a Voidshaper, it removes one stack of Cosmic Shell.
That means for every Voidshaper you want to remove, you need:
- Two Void Marked players
- Both dispelled on top of the same Voidshaper
So the practical play is simple: Call which markers are getting “dispelled,” and have Void Marked players move to those tiles. Then dispel them there.
As long as people don’t randomly dispel in the raid, this part is very stable. You usually get more Void Marked debuffs than you actually need, so it’s mostly about clean communication and not wasting them.
Add Priority Changes
The wave you end up actually fighting still has the same general “stack and cleave” approach, but target priority matters more on Mythic.
The Abyssal Voidshaper you are fighting needs to be priority damage, because its energy bar fills faster on Mythic. If it reaches 100 energy and turns into the gym bro version, you are very likely wiping because it has a lot of HP and the whole wave spirals out of control.
You also get a new add, Abyssal Malus. It still has Pitch Bulwark, so you still need interrupts on that, but it also casts Black Miasma. If Black Miasma goes through, several players get their haste reduced by 70% for 15 seconds, which feels horrible and can easily slow you down enough to cause a chain reaction.
So your priorities look like this:
- Kill the Voidshaper before it hits 100 energy
- Interrupt Pitch Bulwark
- Interrupt Black Miasma
- Everything else gets cleaved down
Voidmaws on Mythic
Voidmaws still do the same annoying thing, but Mythic makes it more punishing.
Once a Voidmaw hits 35% HP, it will slowly walk toward a claimed spot. If it reaches one, it heals back to full. They’re slow, so this is mostly a positioning problem. As long as you aren’t tanking them right next to a claimed tile, they usually won’t get close.
Everything else is still Heroic
Outside of Cosmic Shell and the extra add spell, the rest of the fight is basically the same:
- Dodge the spikes and circles
- Keep the board under control
- Don’t let the boss camp claimed tiles
- Soak what needs soaking
- Kill the adds cleanly and move on
If you handle your tic tac toe calls properly, kill the Abyssal Voidshaper that spawns and do your Void Marked dispels on time and in the correct places, this boss will die.
