The Nullaeus Challenge and Arcanovoid Construct
Nullaeus is a solo boss encounter in his own instanced lair, introduced with Midnight Season 1 as a peak-difficulty delve challenge. The fight scales with tier — at Tier 11, damage output, survivability, and interrupt discipline all matter in ways that lower tiers don't force. The full reward chain includes three achievements: My Shady Nemesis for the first attempt, Lighting the Dark for clearing a lair mechanic, and Let Me Solo Him: Nullaeus for the actual Tier 11 solo kill.
Completing the chain unlocks Arcanovoid Construct — a mechanical arcane mount — plus the Ominous title and the Nullaeus Domaneye transmog appearance. When Midnight Season 2 opens, the mount becomes a Feat of Strength and exits the regular reward pool, so the window for normal unlock closes at season rollover.
About Arcanovoid Construct Mount Boost
The Arcanovoid Construct mount boost is a Midnight Season 1 mount unlock service that clears the Tier 11 Nullaeus solo challenge, completes the Let Me Solo Him: Nullaeus achievement chain, and delivers the Arcanovoid Construct mount, Ominous title, and Nullaeus Domaneye transmog before the season closes and the reward converts to a Feat of Strength.
BuyTheWin runs Nullaeus services through rotations that already push delve tiers daily, so the Tier 11 entry isn't a bottleneck — if your character doesn't have Tier 11 unlocked at checkout, we unlock it as part of the service. Piloted sessions use Premium VPN region-matched to your account, and the mount registers account-wide immediately after the kill.
FAQ
Why is Self-play not available for this service?
The achievement is specifically solo — no other players or pets-on-timer can be in the lair when Nullaeus dies. That rules out a Self-play-with-booster format. Only piloted or remote desktop work for a valid Let Me Solo Him: Nullaeus completion.
What happens to the mount if I don't get it this season?
After Midnight Season 2 launches, the Arcanovoid Construct converts to a Feat of Strength. Existing owners keep it, but no new accounts can unlock it through normal delve content — a common pattern for seasonal mounts in WoW. Orders placed in the final weeks of the season get scheduling priority.
Can I do this under 250 ilvl?
Technically possible on meta classes with perfect execution, but the enrage timer turns hard at Tier 11. Most sub-250 attempts stall on the damage check before the last phase. If your character is under 250, we add a gearing pass as a paired service so the kill isn't a coin flip.
