Nulleaus Nemesis Boss Guide
This was done on the PTR, and changes may occur before the Delve Nemesis is available on live servers.
Good luck to everyone going for the Fabled Let Me Solo Him: Nullaeus achievement!
Nullaeus Delve
The Nullaeus Delve is available at /way #2405 61.2 71.2 in Voidstorm. Nullaeus is available on two difficulties ? (Easy) and ?? (Hard). Much of the difficulty of this fight comes from white swings meaning tanks are preferred as they never have to worry about their survivability.
Here's a video of ? difficulty on the PTR, but ?? is the same with higher damage and health..
Nullaeus Abilities on ? (Easy)
Nullaeus only has a few abilities on ? difficulty.
Emptiness of the Void is an interruptable cast on a 20 sec cooldown that does 330k AoE damage.
Edit: This has been hotfixed to be a variable cooldown now which should match your interrupt.
Devouring Essence - DoT effect that can be dispelled by Valeera in healer spec
Melee swings hit for ~60k on ? difficulty and ~120k on ?? difficulty on DPS.
At 75%, 50%, and 25% health, Nullaeus goes untargetable and starts a long channel, activating a new environmental effect for the rest of the encounter, and summoning adds.
75% Health
At 75% health, Nullaeus summons 2 Razorshell Ravager. They try to leap on the player using Spiny Leap which can be dodged, and Jagged Rip which applies a high damage bleed. However, Jagged Rip only has a 15 yard range and is a fervent strike meaning if you outrange and only Valeera is in range, they will instead cast it on Valeera.
Nullaeus activates the first Void Orb, which will periodically cover lanes of the arena in goop for the rest of the encounter.
50% Health
At 50% health, Nullaeus summons 7 Spitting Tick. These creatures spit on you and can be AoE'd down easily.
Nullaeus activates the second Void Orb, which summons a Gravity Well which traverses the area, trying to pull you in.
25% health
At 25% health, Nullaeus summons an Enslaved Voidcaster. This mob has a lot of health, and spams Shadow Bolt (which hits for 55k) and occasionally casts Shadow Crash forcing you to move. If you decide to interrupt Shadow Bolt to reduce damage, make sure you have your kick up for the next Emptiness of the Void. This mob also curses players with Curse of Hesitation for 5 minutes, but will reapply it multiple times.
