Nullaeus is the Season 1 Nemesis of Bountiful Delves in WoW Midnight, an arena-style boss that opens up inside Torment's Rise in the southeastern Voidstorm zone. Summoning him costs one Beacon of Hope and a Tier 11 (or Tier 8) Bountiful Delve run, and the fight has been the centerpiece of Midnight's solo-progression conversation since 12.0.5 went live. The first kill on either tier hands out 30 uncapped Hero Dawncrests; the Tier 11 solo kill is the only way to drop the season-exclusive Arcanovoid Construct mount.
The rest of this guide breaks each phase down, then runs through the reward ladder and the solo path.
Nullaeus is not a standard delve boss. You unlock the arena by consuming a Beacon of Hope inside a fully cleared Tier 8 or Tier 11 Bountiful Delve. There is no daily lockout on the summon itself, only the Beacon supply, which is what limits attempts per week.
Two sources feed your Beacon stockpile:
The Beacon is bind-on-account, so a main-character grinder can stockpile and hand the Beacon over to whichever character is going in for the attempt. Players who want to skip the Tier 7 to Tier 10 gating often pair a tier-unlock service with a Beacon purchase the same week so the first attempt is a Tier 11 try rather than a Tier 8 warm-up.
Both difficulties drop the same boss; only the ceiling and a few of the reward gates differ.
The interrupt and dispel windows are identical between tiers; only the damage scaling and the soft-enrage timing tighten at Tier 11. A group running 5 ilvl below the recommendation can still clear Tier 11 if interrupts on Emptiness of the Void are clean and Devouring Essence stacks never pass 4 on the same player.
Outside the intermissions, Nullaeus runs a three-ability cycle:
The cycle order is Devouring Essence, Emptiness of the Void, Imploding Strike, repeat until the next intermission. Both Emptiness and Devouring Essence are on the same interrupt school, so a dedicated interrupt rotation between two players is enough to keep both locked down.
Each intermission spawns adds and locks in a permanent arena mechanic that persists for the rest of the fight. The mechanics stack: by the 25% phase, the Tier 11 arena is running Null Zone plus Gravity Well plus Umbral Rage simultaneously, and that is the part of the fight where most pugs collapse.
The escalation order:
The single biggest pug-killer is the Gravity Well + Null Zone interaction inside the 25% phase: kiting the Voidcaster across an arena where a third of the floor is unsafe and an orb is actively pulling you onto an Emptiness of the Void cast. Plan defensive cooldowns so each tank cycle has at least one major mitigation paired with each Imploding Strike during the 25% phase.
Solo and duo runs lean heavily on Brann Bronzebeard, the Delve companion NPC. Brann has three roles (Tank, Healer, DPS) and an independent level you grind through repeated Delve runs.
Brann's role can be swapped at Delver's Headquarters in Silvermoon between attempts. Bring a stack of currency to reroll his Curio loadout if a particular run pattern is not clicking; the Delve Curio system is the only meaningful between-attempt power lever once your gear is settled.
Solo Tier 11 is the only path to the Arcanovoid Construct mount, and the bulk of the conversation in Midnight's Delve community right now is about which class brings the fastest clean kill.
The standard solo setup is a Guardian Druid, Blood Death Knight, or Vengeance Demon Hunter with a Healer Brann at the highest available level. Other tank specs can clear the fight; the three above have the smoothest self-sustain pattern against the Imploding Strike and Emptiness of the Void cadence.
Beyond class pick, the solo run focuses on three habits:
Mount collectors who do not want to learn the fight personally can order an Arcanovoid Construct mount run as a service; the requirement is your character being on the same realm/region for the loot trade-window.
The full set of unlocks across both tiers:
| Achievement | Gate | Reward |
|---|---|---|
| My Shady Nemesis | First Nullaeus kill on any tier | Nullaeus Domaneye helm transmog, 30 Hero Dawncrests (uncapped) |
| Nulling Nullaeus (seasonal quest) | Complete the seasonal quest tied to the first kill | Dominating Victory toy |
| Lighting the Dark | Tier 11 Nullaeus kill (any group composition) | "Ominous" title |
| Let Me Solo Him: Nullaeus | Solo Tier 11 kill | Arcanovoid Construct mount |
| Fabled Let Me Solo Him: Nullaeus | First 4,000 region-wide solo Tier 11 clears | "Fabled Vanquisher of Nullaeus" title |
Players running multiple characters can browse the delve boost catalog for tier unlocks, weekly Beacon-of-Hope completions, and full-clear services that let alts collect the first-kill rewards without re-grinding the gear path.
Torment's Rise sits in the southeastern part of the Voidstorm zone at approximately 61, 71, between Nexus-Point Xenas and Obscurion Citadel. It is one of the Tier 11 Bountiful Delves on the season's roster, but Nullaeus only appears when you summon him with a Beacon of Hope.
One Beacon per week from the Nightmare Prey weekly is the floor. Layered onto that, 5,000 Undercoins per extra Beacon means an active Undercoin grinder can stack two or three attempts per week. Solo learners typically average four to six tries before a clean Tier 11 kill, so plan for two to three weeks of Beacons per character.
The Beacon of Hope is consumed on summon, not on death. If the group wipes through all Delve lives, the Beacon is gone and Nullaeus despawns. There is no soft-reset, so opening the arena with a clear interrupt assignment is more important than topping off ilvl.
No. The recommended ilvl is ~274, which is hit comfortably by a player with Hero-track Bountiful Delve and Mythic+ gear at +8 or higher. The fight is execution-gated, not gear-gated; a 271 ilvl player who interrupts every Emptiness of the Void will clear faster than a 280 player who misses one.
No. The mount is gated behind the solo Tier 11 achievement specifically. A group clear earns the "Ominous" title but does not roll the mount.
No, and that is the headline reward of the first Nullaeus kill. The 30 crests sit outside the weekly Hero crest cap, so they accelerate your upgrade ceiling immediately on top of whatever you have already earned that week.
Guardian Druid, Blood Death Knight, and Vengeance Demon Hunter cover the Tank route with the cleanest self-sustain pattern against Imploding Strike and Emptiness of the Void. Healer specs can also solo with enough patience; the fight becomes a long DPS check against Umbral Rage's stacking damage at 25 percent. DPS specs solo with the most difficulty because they cannot soak Imploding Strike directly.
Nullaeus is Midnight's first true "delve raid boss" in everything but lockout. The fight rewards interrupt discipline, defensive cooldown rotation, and movement discipline far more than item level, and the rewards on offer (the helm, the toy, the title, and the mount) make it one of the highest-prestige solo achievements in the game right now. The Beacon-of-Hope economy is the only real bottleneck once your group has a clean run pattern; budget two to three weeks of Beacons per character and the kill is well inside the reach of any player who already farms Tier 8 to 10 Bountiful Delves.
