Abyss Worm Mount Guide

Updated 24 May 2026 | Author: Invord | ~6 min

The Abyss Worm is a terrifyingly magnificent mount that seems to have crawled straight from the deepest trenches of the Great Sea. This massive, segmented worm with glowing runes and a cavernous maw was the pinnacle aquatic-themed reward from Legion's Tomb of Sargeras raid. Its unique, undulating animation and imposing size make it a standout trophy, symbolizing mastery over the naga and Old God forces that threatened Azeroth.

Acquiring the Abyss Worm presents a unique farming advantage: it drops from a specific boss, Mistress Sassz'ine, and each difficulty level counts as a separate loot chance. This means you can run Normal, Heroic, Mythic, and even the Looking For Raid (LFR) version each week on the same character for four independent rolls at its 2% drop rate.

  • Added in patch: 7.2.0 "The Tomb of Sargeras"
  • Type: Flying
  • Source: Raid Drop
  • Requirements: Level 20
  • Repeat attempts: 4 per week per character (LFR, Normal, Heroic, Mythic)

How to Get Abyss Worm

Abyss Worm Mount

The Abyss Worm drops from Mistress Sassz'ine, the third boss within the Tomb of Sargeras raid. The drop chance is consistent across all difficulty levels at approximately 2%. Crucially, raid size does not matter—you can solo it easily at max level, and the chance remains the same whether you're alone or in a group.

The core strategy is to exploit the separate lockout system: kill Sassz'ine on LFR, Normal, Heroic, and Mythic difficulty every week on each of your farming characters. This systematic approach turns a low-probability drop into a manageable, scheduled farm with predictable progress.

Want to skip the weekly raid circuit? Our experts can run the full lockout for you. Check out our Abyss Worm acquisition service for a guaranteed and efficient path to this monstrous mount.

Accessing Tomb of Sargeras

The raid entrance is located on the Broken Shore in the Broken Isles. There are no attunement quests required.

For Normal, Heroic, and Mythic:

  1. Travel to Dalaran (Broken Isles) and use the portal to the Broken Shore.
  2. Fly to the coordinates /way Broken Shore 64, 21.4 to find the massive tomb entrance on the coast.

For Looking For Raid (LFR):

You cannot walk into the LFR version. Instead, you must queue for it via Archmage Timear in Dalaran (Broken Isles).

  1. Find Archmage Timear near the Violet Hold entrance at /way Dalaran Broken Isles 63.6, 55.6.
  2. Speak to him and select "The Gates of Hell" wing. This wing contains the first three bosses, including Mistress Sassz'ine.

The Route to Mistress Sassz'ine

Sassz'ine is the third boss. You must defeat the first two bosses to reach her chamber. The path is linear but involves some vertical navigation.

  1. Defeat Goroth: Enter the raid and follow the path to the first boss, a giant fel infernal. Defeat him.
  2. Descend into the Tomb: Behind Goroth's platform, look for a large crack/fissure in the ground. Jump down into it. This leads to a cavernous area.
  3. Defeat the Demonic Inquisition: Follow the path until you reach the second boss encounter (two demons on platforms). Defeat them.
  4. Navigate to the Abyss: After the Inquisition, continue along the main path until you enter a long, straight corridor. At the end of this corridor, turn right.
  5. Find the Staircase: You will see a staircase leading downward. Go down the stairs and follow the winding path through the watery, naga-infested tunnels.
  6. Face Mistress Sassz'ine: This path will eventually open into her circular arena. Engage and defeat her for your chance at the Abyss Worm.

Multi-Character Strategy: This is where you massively accelerate your farm. Each character can provide 4 attempts per week. Maintaining a roster of 5 alts means 20 weekly attempts at the 2% drop. Organize a weekly routine to clear all four difficulties on each character.

Alternative Acquisition: Black Market Auction House

For collectors who prefer a direct transaction over weekly RNG, the Black Market Auction House (BMAH) frequently lists the Reins of the Abyss Worm. As a sought-after raid mount from a popular expansion, it commands a significant price but offers a guaranteed result.

When available, bidding often starts between 500,000 - 800,000 gold, with final prices capable of reaching well over a million gold on competitive realms. Its distinctive model and relative rarity ensure it remains a high-value BMAH commodity.

Bidding Strategy:

  • Consistent Checks: Monitor the BMAH daily. High-value raid mounts like this one can appear and sell within a single refresh cycle.
  • Pre-allocated Gold: Keep the gold for a maximum bid on the character you intend to use, as moving large sums between characters can be slow and risky during an active auction.
  • Realm Research: Prices can vary between connected realm groups. If you have characters on multiple groups, you might find a better deal.
Competing on the BMAH requires deep pockets. We offer secure gold acquisition services to ensure you have the capital to win the Abyss Worm auction.

Essential Addons for Farming

Managing weekly lockouts across multiple characters and difficulties requires precision. These addons are crucial for efficiency:

  • SavedInstances: Non-negotiable for raid farming. This addon provides a perfect overview of which characters have completed which difficulty of Tomb of Sargeras for the current week. It eliminates guesswork and ensures no lockout is missed.
  • Rarity: Tracks your total kills of Mistress Sassz'ine across all characters and difficulties, giving you a clear picture of your progress against the 2% odds. Essential for maintaining perspective during a long farm.
  • Angry Keystones / Premade Groups Filter: While not for the farm itself, these can help you quickly form or find groups for the harder difficulties (Heroic/Mythic) if you're not yet geared to solo them effortlessly.

These tools provide the organization and data needed to run a high-volume, multi-character raid farm effectively, turning a complex schedule into a simple checklist.
