Players searching for Arcanovoid Construct usually want three things: how to get it, whether it is still obtainable, and whether the grind is worth the time. This guide covers the exact acquisition method, location, requirements, practical farming tips, and a collector-focused assessment so you can decide whether to push for this prestige Delve reward.

Quick Answer

What it is: a seasonal prestige mount awarded by the feat of strength Let Me Solo Him: Nullaeus.

How to get it: defeat the Delve Nemesis Nullaeus solo on the required Tier difficulty during Midnight Season 1 and earn the achievement that grants the mount item.

Rarity and why players want it: it is a prestige, limited-time reward with a void-arcane appearance that marks you as someone who completed a difficult, skill-gated challenge. Because it is tied to a seasonal nemesis achievement, it is higher prestige than most vendor or currency mounts.

Mount Overview

The Arcanovoid Construct is a void-infused arcane guardian mount with a mechanical chassis and void wings. Its aesthetic reads as a hybrid of the arcane guardian model with additional void effects, which appeals to collectors who want mechanical mounts with a void theme. It appears in the Midnight expansion and is categorized as an achievement reward rather than a vendor or drop.

Collector appeal stems from three factors: it is account-wide once learned, it is tied to a solo feat of strength, and it is seasonal. That combination makes it desirable for players who collect prestige mounts or enjoy showing completion of difficult seasonal content.

How to Get Arcanovoid Construct

Getting this mount is straightforward in description, but challenging in execution. The mount is rewarded by the achievement Let Me Solo Him: Nullaeus, which requires you to defeat the Midnight Season 1 nemesis Nullaeus in Torment’s Rise as the only player in your party on the specified Tier difficulty before the season ends. After the achievement triggers, the mount is granted via an in-game item that teaches the mount.

Step-by-step acquisition

1. Unlock the Torment’s Rise Delve and the appropriate higher difficulty Tier for the achievement. Higher difficulties often require clearing previous Tiers with lives remaining to unlock.
2. Prepare Valeera as your companion and set her curios per the encounter recommendations, or choose a class and spec that can reliably survive long fights while handling adds and interrupts.
3. Enter Torment’s Rise, locate Nullaeus, and defeat him solo on the required Tier. Do not have any other players in your party when the achievement condition must be satisfied. Upon success you will earn the achievement and the mount item.

Why it is not a drop or vendor item

This mount is granted directly by the achievement reward, not by a random mob drop, vendor purchase, or reputation. Because it is an achievement reward, farming strategies focus on reliably completing the solo challenge rather than repeating a loot table.

Location

Nullaeus resides in the Torment’s Rise Delve, which is located in the Voidstorm zone in Midnight Season 1. The entrance sits between Nexus-Point Xenas and Obscurion Citadel, and the Delve is accessible once you reach the required Delver’s Journey progress and Tier unlocks.

• Expansion: Midnight (Season 1)
• Continent/Zone: Voidstorm, Torment’s Rise Delve.
• Activity type: Seasonal Delve Nemesis encounter (single-boss Delve).

Requirements

• Owning the Midnight expansion content and access to Season 1 Delves.
• Unlocking the Torment’s Rise Delve and the Tier difficulty required by the achievement. That typically requires completing certain Tier clears with lives remaining, for example clearing a Tier 7 or Tier 10 to unlock higher difficulties depending on current Season gating.
• Playing the kill solo, with no other players in your party, at the specified Tier difficulty before the start of Season 2.
• Level and gearing expectations. Blizzard and community guides list recommended item levels in the mid-200s for comfortable completion of the Tier target. Exact recommended item level can vary by Tier and class.
• Achievement completion rather than a reputation or currency requirement. The reward is granted by the Let Me Solo Him: Nullaeus achievement.

Farming Tips

Because this is an achievement mount and not a random drop, think in terms of strategies to guarantee a solo kill rather than maximizing kill count. Use the following practical advice to save time.

Optimal party setup and companion use

• Valeera companion setup: many guides recommend using Valeera either as DPS or healer with specific curios like Porcelain Blade Tip and Overflowing Voidspire to simplify add control and dispels. Configure her to complement your playstyle.
• Healer strategy: entering as a healer spec while Valeera performs as DPS can make the fight easier because Nullaeus has high single-target hits and dispellable DoTs. Several players report success by healing themselves and letting Valeera carry the DPS.
• Alternative solo approaches: some classes find the fight easier than others. If you have well-geared alts, try classes and specs with strong self-sustain and reliable interrupts. Method and community posts suggest experimenting with multiple characters if one spec feels unworkable.

Mechanics to prioritise

• Interrupt Emptiness of the Void at all times. It is lethal if allowed to resolve, so keep an interrupt or control available.
• Kill adds during intermission phases quickly. Nullaeus becomes invulnerable during intermissions and spawns adds that must be killed to end the intermission. Prioritise add control to avoid being overwhelmed.
• Manage void zones and orb mechanics by positioning to deny Nullaeus favorable portal alignment. Paying attention to arena geometry prevents unnecessary damage and makes kill windows predictable.

Efficient practice and alt strategies

• Use lower difficulty runs to learn mechanics, then push higher difficulty once you are consistent. Practice the fight on easier Tiers to get a feel for the timings and Valeera interactions.
• Rotate alts instead of repeating the same class dozens of times. Trying a class that naturally handles adds and survivability can shorten the grind. Several community reports note success after switching classes.
• Track Delver’s Journey progress and Tier unlocks and plan attempts for times when you can reliably clear prerequisite content, so you do not waste attempts on an incorrectly unlocked Tier.

Is This Mount Still Obtainable?

The Arcanovoid Construct is a Season 1 Delve reward and must be earned before Midnight Season 2 begins. Blizzard lists the achievement and mount among seasonal Delve rewards that are time-limited to Season 1, so if you miss the window you cannot earn the achievement in the same way after the season ends. Plan attempts while Season 1 is active.

Community guides and boosts confirm the seasonal nature and recommend locking in the achievement during Season 1, because the solo feat of strength and its mount are tied to that seasonal cycle. While Blizzard occasionally reintroduces seasonal rewards or changes access in later patches, you should treat this as time-limited until an official change is announced.

Is It Worth Farming?

Short answer: for collectors who value prestige and seasonal achievements, yes. For players who prioritize convenience mounts or transmog synergy, probably not. The mount’s value depends on your goals.

Consider these points:

• Prestige. Because it is earned by a solo seasonal achievement, it signals mechanical skill, patience, or both. Many collectors prize that visibility.
• Uniqueness. The model is not a wholly new chassis but a void-arcane variant of existing arcane guardian mounts. If you already own similar mechanical or void mounts, the incremental visual upgrade may be smaller. Community discussion notes some disappointment at model reuse but still acknowledges the mount’s prestige value.
• Time investment. Expect multiple attempts if you are unfamiliar with the encounter or are undergeared. However, if you approach the fight with proper Valeera setup or an optimized healer/DPS strategy, several players completed it in a few runs.
• Long-term appeal. Because it is tied to a season, the mount is inherently collectible and will retain value to completionists who prioritize “seasonal feat” mounts. If your collection goals include prestige or season-exclusive mounts, it is worth the push.

Similar Mounts

Trying to match theme, source difficulty, or prestige? Here are 4 mounts to consider with brief reasons.

• Nullaeus Domaneye — a cosmetic helmet reward from the same nemesis runs, pairs visually and thematically. Good if you want more Nullaeus-themed rewards.
• Calamitous Carrion — a Season 1 Mythic+ mount awarded for high rating. Similar seasonal prestige and shows off PvE accomplishment.
• Ominous-themed Delve vendor mounts — vendor-purchasable Delve mounts that are easier to get if you prefer saving time. These share the Delve aesthetic without the solo achievement requirement.
• Arcane Guardian variants — other arcane/mechanical guardian mounts with recolors or void effects. Good if you like the chassis but want multiple colorways. Community posts note the model similarity.

Frequently Asked Questions

1. Can I still get Arcanovoid Construct after Season 1 ends?

No. The mount is a Season 1 Delve reward tied to the Let Me Solo Him: Nullaeus achievement and must be completed before Season 2 begins. Treat it as time-limited unless Blizzard later changes seasonal reward access.

2. Is the mount given as a drop or as an achievement reward?

It is granted by the achievement Let Me Solo Him: Nullaeus. Completing the achievement awards an item that teaches the mount. It is not a random drop or vendor purchase.

3. Can multiple characters on the same account earn it?

Yes. The mount item is bind-to-warband and when learned it becomes account-wide like most mounts, meaning alts on the same account can use it once learned. The achievement itself must be completed per character for the initial entitlement if required by the season mechanics.

4. Can I buy the mount from Undercoin vendors or other sources?

No. This prestige mount is exclusively tied to the solo achievement and is not sold by vendors or through currency. Community boost services exist but that is a third-party service, not an in-game vendor.

5. How difficult is Nullaeus compared to other nemesis fights?

Nullaeus is designed as a strong seasonal nemesis. Many players find it more manageable than some previous nemeses because strategies such as healing while Valeera DPS or careful interrupt management make the fight reliable. Difficulty depends on gear, class, and familiarity. Guides recommend practicing mechanics on lower Tiers first.

6. Will Blizzard ever reintroduce the mount in a future season?

Blizzard controls seasonal reward availability. Official Season 1 messaging states the achievement and its rewards apply before the next season starts. While possible, you should not assume reintroduction unless Blizzard announces it.

7. Can I complete the achievement with a group of NPC companions?

No. The achievement requires you to be the only player in your party. Companion NPCs like Valeera are allowed and are intended to be used, but other players disqualify the solo condition.

8. How long does it typically take to earn this mount?

It varies. Players who come in prepared with the recommended curios, proper Valeera setup, and suitable gear report success in a few attempts. Players unfamiliar with the fight or undergeared may require many tries. Expect anything from a single session for a practiced player to multiple sessions for those learning mechanics.

Final Thoughts

The Arcanovoid Construct is a solid prestige mount for collectors who value seasonal, achievement-based rewards. It is approachable with a clear strategy: unlock the Torment’s Rise Tier, set up Valeera or an appropriate class, and focus on interrupting lethal casts while controlling adds. Because it is only available during Midnight Season 1, prioritize attempts while the season is active if you want this mount in your collection.
