Farming perspective: the Phase-Lost Slateback is a phase-themed, ground-only slateback mount unlocked by tracking down a set of collectible Phase-Lost weapon appearances while Phase Diving in K’aresh. It demands patience and route planning, but the reward is a unique translucent slateback that many collectors prize for its spectral glow and novelty of being tied to the new Phase Diving content.

Quick Answer

What it is: An account-wide ground mount rewarded by the Phase-Lost-and-Found achievement.

How you get it: Complete the Phase-Lost-and-Found achievement by collecting all Phase-Lost weapon appearances from Phase Orbs that spawn while Phase Diving in K’aresh.

Rarity and availability: Still obtainable as of patch 11.2 content, but the achievement requires finding many weapon appearances that spawn from orbs. Community sources note the weapons are limited per orb and that drop rates mean multiple runs will be required.

Why collectors pursue it: The mount’s visual effect is distinctive and thematic with Phase Diving. It also becomes the “default” mount model used while phase-diving once the required cloak talent is unlocked, which gives it practical novelty as well as prestige.

Mount Overview

The Phase-Lost Slateback is a translucent, ethereal-looking slateback mount with a pinkish glow effect that applies to the rider when mounted. It reads as a medium-sized, hoofed mount in the slateback family and visually fits the spectral, phase-themed cosmetics introduced in the K’aresh content. The mount is account-wide and taught by an item that binds on pickup. The item entry lists a requirement of Apprentice Riding to use the mount in normal circumstances.

Because the mount ties directly into Phase Diving rewards, its appeal is both cosmetic and novelty-based. It remains desirable for collectors who chase mount-first achievements and for players who like mounts that change the feel of in‑game traversal when combined with Phase Diving mechanics.

How to Get Phase-Lost Slateback

The mount is awarded for completing the achievement Phase-Lost-and-Found. To earn that achievement you must collect every Phase-Lost weapon appearance that can drop from Phase Orbs while Phase Diving in K’aresh. Phase Orbs appear in the Untethered Space phase of K’aresh, and you must be in Phase Diving to pick them up.

Core steps:

• Unlock Phase Diving by progressing the Ghosts of K’aresh campaign up through Chapter 3, then complete the Phase Diving intro questchain. This grants the Reshii Wraps cloak and the ability to start Phase Diving.
• Equip and upgrade your Reshii Wraps. Community guidance recommends having the Reshii Wraps talent that reveals Phase Orbs (Secrets of the Depths) active to make orbs visible and to allow mounting while phased. Many players report the Rank 3/Secrets of the Depths step as the key unlock for seeing orbs and mounting during dives.
• Phase Dive at a Phase Conduit in K’aresh and run known orb spawn locations. Loot orbs when you see them to get a chance at a Phase-Lost weapon appearance. Repeat until your achievement progress completes and the mount rewards are granted.

Location

All required activity happens in K’aresh, specifically in the Untethered Space phase that you access by using a Phase Conduit while Phase Diving. Orbs spawn across the islands and locations inside K’aresh, with community-posted coordinates and grouped spawn clusters around major conduits and hub points. You will be running between the islands and conduit hubs while hunting orbs.

Requirements

• Access to the K’aresh Phase Diving content (added in the patch that introduced Ghosts of K’aresh). You must have progressed the K’aresh campaign far enough to receive the Reshii Wraps.
• Reshii Wraps cloak obtained and upgraded as needed to unlock the talent that shows orbs. Most guides and players recommend having the Secrets of the Depths upgrade active to reliably see and interact with Phase Orbs.
• Time, patience, and willingness to server hop or run set orbital routes. The achievement requires collecting a broad set of appearances that do not drop from every orb.
• Character level and riding requirements appear in the item entry as normal use requirements. Check your mount tooltip after receiving it for riding specifics.

Farming Tips

Phase Orb farming is route and timing based. Community posts and guide pages have converged on several practical tactics that save time.

• Upgrade the Reshii Wraps first. The Secrects of the Depths/Rank 3 talent makes orbs visible and allows mounting while phased, which greatly speeds routes. If you do not have the cloak talent active, orbs are harder to spot.
• Use a consistent route and server hop. Many players run a fixed loop between 3–6 high‑density spawn points and change realms to force more orb spawns. Wowhead commentors have posted verified coordinates and multi‑portal loops that reliably surface orbs. Server hopping is a common way to reduce overall time per appearance.
• Alternate War Mode on/off runs. Some players switch War Mode during laps to change population dynamics. When population is low, orbs can fail to respawn; running during busier hours increases chances.
• Expect many orb interactions. Community reports vary, but players commonly report needing dozens of orb loots to finish the list. One community note places the chance for a weapon appearance at roughly 20% per orb interaction, and that you always receive an appearance you do not already own. Use that as a planning baseline, not a guaranteed rate.
• Use movement and avoidance consumables. Items such as Untethered Xy’bucha or movement utility help beat mobs and speed runs. Ground-speed classes and abilities (druid travel, shaman ghost wolf) make route loops much faster.
• Check your bags and relog if an item seems missing. Multiple players have reported items failing to appear in their bags until relogging, so check carefully before rerunning routes.

Number of Items Needed and a Note on Discrepancies

There is inconsistent reporting in community sources about how many distinct Phase-Lost appearances are required for the achievement. Wowhead’s Phase Diving guide lists 27 distinct weapon transmogs required, while other outlets and player reports list 28. Many comment threads call out a hidden or missing ‘claw’ appearance that some players had to track down, which helps explain the discrepancy. If you are tracking progress, check the in‑game achievement UI for your current count and consult updated community trackers, because this is one area where player discussion has shown differing counts and occasional bugs.

Is This Mount Still Obtainable?

Yes. The Phase-Lost Slateback was added as part of the patch that introduced K’aresh Phase Diving content and remains obtainable by completing the Phase-Lost-and-Found achievement. It is not a promotional or time‑limited mount as long as the Phase Diving content remains available and unchanged. Always confirm in-game before farming if future patches change achievement requirements.

Is It Worth Farming?

From a collector perspective, the mount is worth farming if you value unique, phase-themed cosmetics and the novelty of a mount tied directly to exploration mechanics. The mount is visually distinct and carries prestige, since it requires targeted farming rather than straightforward vendor purchases or easy drops.

From a pure time-efficiency perspective, plan for multiple hours of route-running. If you are short on time, this mount is a mid-to-long-term project. If you enjoy route-based farming and server-hopping or you are already working on other K’aresh collection tasks, the Slateback is a sensible target. The achievement-based nature prevents easy bulk farming across alts unless each alt has access to Phase Diving and the Reshii Wraps upgrades.

Collector Notes

Collectors should note a few behavior quirks. While phase-diving, the Slateback’s effect can override other mount appearances, which some players find immersive and others find annoying. The mount is ground-only in its base form, and community reports indicate mounting behavior can dismount you when leaving a phase if you used the mount while phased. If you care about clean mount behavior across contexts, that may matter to you. On the plus side, the mount also gives your character a distinct pink glow while mounted, which makes screenshots stand out.

Similar Mounts

• Pearlscent Krolusk — Similar in that it has an unusual coloration and collector appeal. Recommended for players who enjoy mounts that look out of the ordinary. (Comparable novelty.)
• Reins of the Pale Thorngazer — Another spectral/ethereal mount with a translucent effect. Good for collectors who like ghostly visuals.
• Phase-Hunted Krolusk — If you like phase-themed or event-tied mounts, choose this as a complementary look.
• Untethered Skymote — If you enjoy mounts tied to new traversal mechanics or expansion-specific features, this is an alternate route of collecting similar ‘mechanic-linked’ mounts.

Frequently Asked Questions

Can I still get the Phase-Lost Slateback?

Yes. It is obtained through the Phase-Lost-and-Found achievement tied to Phase Diving in K’aresh.

How many Phase-Lost appearances do I need to collect?

Community sources disagree. Some official trackers and guides list 27, while other sources and player reports list 28. Check your in-game achievement progress and community trackers to confirm.

Do I need to upgrade the Reshii Wraps to get orbs?

You need to unlock Phase Diving by getting the Reshii Wraps and completing the Phase Diving intro. The Reshii Wraps talent that makes orbs visible and allows mounting while phased is highly recommended and effectively required for efficient farming.

Can multiple characters on my account farm this quickly?

Each character typically needs access to the Phase Diving unlocks. Some players report shortcuts for alts if the main has progressed the campaign, but most alts will need to at least claim and equip the Reshii Wraps and complete relevant quest steps. Confirm on each alt before assuming you can simply port the progress.

What is the drop rate for weapon appearances from orbs?

Exact rates are not officially published. Community estimates and guide notes suggest roughly a 20% chance per orb to contain a weapon appearance, but this should be treated as an informal estimate. You will need multiple orb loots.

Can I farm the orbs solo?

Yes. Many players farm solo by running a loop of known spawn points and server hopping. Solo runs are slower than coordinated group setups but entirely viable if you prefer solo play.

Will the mount work while phase-diving?

In normal circumstances the mount appears ground-only, but when your Reshii Wraps are upgraded to show orbs and allow mounting while phased, any mount you call while phase-diving will take on the Slateback’s visual while in the phase. That behavior is tied to the cloak upgrades and phase state.

Is the mount account-wide?

Yes, the item that teaches the mount is bind-on-pickup and the mount is account-wide once learned.

Final Thoughts

The Phase-Lost Slateback rewards dedication to Phase Diving exploration and route optimization. If you enjoy route-based farming and the idea of a phase-linked cosmetic, this mount is a satisfying target that also unlocks a quirky traversal aesthetic while phase-diving. Expect to invest several hours, use the Reshii Wraps upgrade to speed the process, and consult community route lists for the most efficient runs. Good luck on the orb loops and on filling the final slot in that achievement tracker.
