Tanks
- Break the walls using Calamitous Strike.
- After Calamitous Strike the boss will always use Echoing Fissure. Make sure the boss doesn’t move to the new section before he has cast this.
- Taunt swap after each Calamitous Strike.
- Sunder Shadow pulls your soul from your body allowing you to pass through walls. When Neltharion ends his cast, your soul will fly back to your body breaking any walls in between.
- In phase three Calamitous Strike should be aimed at the outside wall instead.
Healers
- Umbral Detonationdeals more damage each time it is cast.
- Players who are targeted with Corruption should be thrown some absorbs and HoT’s early before they become hostile.
DPS
- Focus down Voices From Beyond adds as soon as they become attackable.
- Two target cleave is good for phase two.
- some AOE helps in phase three to stop the adds building up uncontrollably.
- Save Heroism/Bloodlust for phase three.
Phase One
Neltharion will follow a sequence of spells for this entire phase until he reaches 70% health. He will separate the room into sections with Twisted Earth. All players should make sure they are within the same section that Neltharion is in, otherwise they will be out of line of sight of other players and the boss.
He will mark several players with Rushing Darkness. This spell knocks players back and silences anyone hit. It can break parts of the Twisting Earth walls, but this should be aimed at the outside edge of the area instead. This is because every chunk of the wall that is broken causes a DoT on all players that stacks, and having many people breaking walls will very quickly wipe the group.
Some players will also be targeted by Volcanic Heart, which is a large orange circle that erupts after a few seconds. These players should move to the sides and edges of the available space, while everyone else should stay close to Neltharion. Volcanic Heart does leave a nasty DoT that stacks, so you really do not want to be standing in one if you do not have to.
The tank swap in this fight is Calamitous Strike. This ability knocks the main tank back, breaking any walls they fly into. This is very useful for manoeuvring round to new sections before the boss casts Echoing Fissure. When one tanks gets knocked back, the other tank should instantly taunt and pull the boss as far from the opening as possible. Neltharion will always cast Echoing Fissure straight after Calamitous Strike, which is a large AOE that will cause massive damage to anyone hit and leaves a large growing puddle. Once the boss has been brought below 70% prepare for phase two.
Phase Two
Everyone should group closely once again as Neltharion will break down all existing walls and rebuild them into 3 main areas and a small middle section. He still casts Rushing Darkness and Volcanic Heart like in phase one, and these should be dealt with the same way.
Three Voices From Beyond will spawn, shadowed and currently unattackable. Players will eventually have Corruption cast on them. This is a kiss curse as it allows them players to attack the Voices From Beyond and break their concealment, however it also lets anyone else in the raid attack them, meaning your own team can accidentally (or otherwise…) harm and even kill them. Because of this, everyone should be extremely careful, and no body should stand near the Voices From Beyond unless they are under the effects of Corruption.
The best way to break the walls in this phase is with Sunder Shadow, which is the taunt swap ability for phase two. This works slightly different to Calamitous Strike in that this time, the boss will hit the tanks soul out of their body and pull it back into their body a few seconds later. During this brief moment, tanks can run through the walls. When their soul is pulled back to their body, it will shatter any walls in between them.
During this phase Neltharion will cast Umbral Annihilation periodically. Every time he does this it will deal 100% more damage. This acts as a soft enrage as eventually this will one shot players if the group takes too long. This phase will end when all three Voices From Beyond are killed and he has reached 35% health.
Phase Three
Once again the boss will begin by breaking down any walls and rebuilding them. This time players want to break as few walls as possible due to each one spawning a portal under each one. These portals will spawn Twisted Aberration enemies. By themselves these enemies aren’t particularly dangerous, but in large groups they can shred a tank in mere moments. For every 2 seconds these adds are alive, their damage is increased by 75%. This means if just a few of them stay alive for 10 seconds, each will be dealing 375% more damage with every attack making them extremely deadly to let linger.
On top of this, Neltharion will cast Sunder Reality which breaks several Twisted Earth walls, spawning portals naturally as the fight continues. This is managed easier with Neltharion’s last ability Ebon Destruction which is a 12 second cast that kills anyone it hits unless they are standing in a portal. Standing in the portals reduce all damage and healing dealt and received by 99% but Ebon Destruction will close any portals stood on when the cast is complete. From here it is a DPS race to kill him before you run out of portals or get overwhelmed by Twisted Aberration enemies.
