WoW Fathom Dweller Mount Boost

What Your Fathom Dweller Boost Covers

Depending on the selected offer, your service can include:

• Fathom Dweller mount completion

• Kosumoth the Hungering secret attunement

• Weathered Relic progression

• All required Hungering Orbs

• Correct orb sequence completion

• Unlocking DANGER: Kosumoth the Hungering

The final mount can only be obtained when Fathom Dweller is the active Kosumoth World Quest reward for your region.

How to Get the Fathom Dweller Mount

Fathom Dweller comes from the hidden Kosumoth the Hungering World Quest introduced with Legion.

Before the World Quest becomes available, your character must complete the secret attunement.

The main progression includes:

1. Finding Drak'thul on the Broken Shore.

2. Obtaining the Weathered Relic.

3. Returning to Drak'thul and completing the required interaction.

4. Activating 10 hidden Hungering Orbs across the Broken Isles in the correct order.

5. Returning to the final orb near Drak'thul.

6. Unlocking DANGER: Kosumoth the Hungering.

7. Defeating Kosumoth when Fathom Dweller is the active World Quest reward.

8. Receiving the Fathom Dweller mount.

This is a secret-progression mount rather than a normal rare-drop farm.

Choose Your Fathom Dweller Service

Select the package that matches your current progress.

Full Secret + Mount Completion

Choose the complete service if your character has not unlocked Kosumoth yet.

This can cover the full attunement route and final mount completion when the Fathom Dweller reward is available.

Kosumoth Attunement Only

Choose this option if you want the complete hidden secret unlocked now but the mount is not currently the active regional reward.

Once attuned, your character can complete the World Quest when Fathom Dweller becomes available.

Mount Completion Only

Already completed the secret and unlocked Kosumoth?

When Fathom Dweller is the active reward, choose a final-completion offer covering the required World Quest and mount unlock.

Remaining Secret Progress

If your character has already started the secret, a custom offer may cover only the remaining steps where your existing progress can be confirmed.

Hungering Orbs & Kosumoth Attunement

The core of the secret is a sequence of 10 Hungering Orbs hidden across several Legion zones.

They must be activated in the correct order.

The route takes the character through areas including:

• Azsuna

• Stormheim

• Val'sharah

• Broken Shore

• Highmountain

• Eye of Azshara

Some orbs are hidden inside caves, underwater locations, or difficult-to-see areas.

Skipping the required sequence can prevent the secret from progressing correctly, so this service follows the complete attunement route rather than simply traveling directly to Kosumoth.

Fathom Dweller World Quest Reward

Unlocking Kosumoth does not automatically mean the mount is immediately available.

The World Quest DANGER: Kosumoth the Hungering can reward either:

• Fathom Dweller — aquatic mount

• Hungering Claw — battle pet

The active reward is shared across the applicable region and changes between World Quest rotations.

This means there are two separate parts to the service:

Attunement unlocks access to Kosumoth's World Quest.

Mount completion is performed when Fathom Dweller is the active reward.

We should not advertise immediate guaranteed Fathom Dweller completion when the mount reward is not currently available.

An Aquatic Secret Mount

Fathom Dweller is an aquatic mount designed for underwater travel.

It is not a standard flying or ground mount.

The mount can be summoned underwater and provides increased aquatic movement speed, making it both a collector reward and a distinctive water-travel mount.

Its unusual appearance and hidden acquisition path also make it one of Legion's recognizable secret collectibles.

Fathom Dweller vs Other Secret Mounts

This product is dedicated specifically to Fathom Dweller and its Kosumoth secret.

Other secret mounts use their own acquisition routes.

For example:

• Lucid Nightmare uses a long puzzle chain and Endless Halls

• The Hivemind uses a coordinated multi-player secret

• Riddler's Mind-Worm uses a separate clue sequence

• Long-Forgotten Hippogryph has its own hidden crystal objective

Those mounts should remain under their own dedicated products rather than being bundled into this page.

Fathom Dweller Boost vs WoW Mounts for Sale

Fathom Dweller is earned through gameplay.

It binds when obtained and is not a normal transferable mount item that another player can simply sell to your character.

Use WoW Fathom Dweller Mount Boost when this specific secret mount is your objective.

Use WoW Mounts for Sale only for eligible tradable or transferable mount items.

This keeps gameplay-earned mount services separate from direct item purchases.

How It Works

1. Select your WoW Retail region.

2. Check whether your character has already unlocked Kosumoth.

3. Choose full progression, attunement-only, remaining progress, or mount completion.

4. Confirm whether Fathom Dweller is currently the active World Quest reward.

5. Review the objectives included in the seller offer.

6. Proceed directly to checkout.

7. Provide your existing secret progress when requested.

8. Complete the remaining attunement steps where necessary.

9. Complete Kosumoth's World Quest when the Fathom Dweller reward is available.

10. Unlock the Fathom Dweller mount.

Requirements

Before ordering, check:

• World of Warcraft Retail account

• Correct EU or US region

• Character able to access Legion zones

• Current Kosumoth attunement progress

• Any Hungering Orbs already completed

• Current regional World Quest reward

• Seller-specific service conditions

The Kosumoth attunement is character-specific, so the service should be completed on the character intended to access the World Quest.

If Hungering Claw is currently the active reward, the secret can still be prepared, but the final Fathom Dweller completion must wait for a mount-reward rotation.
