Invincible's Reins

Invincible's Reins is one of the most coveted mounts in World of Warcraft. Invincible is the legendary horse of Prince Arthas Menethil, who served his master both in life and in death. The mount looks like a winged undead steed with a spectral glow, a semi-transparent body and glowing blue eyes. Obtaining Invincible rewards the Invincible's Reins achievement from the "Mount Feats of Strength" category.

Invincible drops from The Lich King — the final boss of the Icecrown Citadel raid in Icecrown (Northrend). The mount is only available on 25 Heroic difficulty, with a drop chance of around 1%.

• One of the rarest mounts in the game — a drop chance of around 1% with one attempt per week per character. Many players farm Invincible for years across a dozen alts
• Iconic appearance — Arthas's spectral winged horse is instantly recognizable and is a symbol of one of the main villains of the Warcraft universe
• A Feat of Strength — obtaining the mount rewards a unique achievement that is visible to all players
• Flying and ground mount — Invincible works as both a flying and ground mount, with speed scaling to your riding skill
• Account-wide — once obtained, the mount appears in the collection of all your characters

Requirements

• A level 90 character (recommended for the fastest possible run, although a solo run is possible as early as level 50)
• Riding skill: Apprentice (ground mode) or Expert (flying mode)
• Raid difficulty: 25 players, Heroic mode — the mount does not drop on other difficulties

How to Get to Icecrown Citadel

1. Head to Dalaran (Northrend). The portal is available from Stormwind or Orgrimmar
2. From Dalaran, fly south into the Icecrown zone
3. The raid entrance is located on the southern side of Icecrown Citadel

4. Before entering the raid, set the difficulty: right-click your character portrait, choose "Dungeon Difficulty" → "25 Player (Heroic)"

Step 1: Set the Difficulty

Before entering the raid, make sure 25 Player (Heroic) difficulty is selected. This is the only difficulty on which the mount drops.

Step 2: The Lower Spire

Enter the Citadel and clear the first four bosses:

1. Lord Marrowgar — the first boss, dies instantly to a level 90 character
2. Lady Deathwhisper — wait for the intro dialogue to finish, then attack
3. Gunship Battle — get into the cannon before the fight begins, quickly build up Heat (ability 1) to 90, then fire (ability 2) at the enemy gunship. This lets you finish the fight in a few seconds
4. Deathbringer Saurfang — a simple fight, killed in a single hit

Step 3: The Plagueworks

After Saurfang, proceed into the Plagueworks. There are three bosses here:

5. Festergut — after the victory, activate the valve in his room
6. Rotface — after the victory, activate the second valve
7. Professor Putricide — available after activating both valves

Step 4: The Crimson Hall

Move on to the Crimson Hall:

8. Prince Valanar — three bosses at once, all die instantly
9. Blood-Queen Lana'thel — the fight starts automatically when you approach

Step 5: The Frostwing Halls

10. Valithria Dreamwalker — this boss can be skipped. Run along the right wall of the room without engaging in combat and head for the elevator behind it. If you have healing abilities, you can heal her, but this is not required to obtain the mount
11. Sindragosa — an undead dragon, dies instantly

Step 6: The Frozen Throne

12. The Lich King — the final boss. Attack him until his health drops to 10%. At this point the "Fury of Frostmourne" ability triggers — this is a game mechanic that "kills" your character. Do not leave the raid and do not release your spirit. After a few seconds Highlord Tirion Fordring will resurrect you. After his line "Rise up, champions of the Light!" the Lich King will be stunned — deliver the final blow

Loot the Lich King's body. If Invincible's Reins is in the loot — congratulations.

Time per Run

A full clear of Icecrown Citadel on a level 90 character takes 5-10 minutes depending on your class and knowledge of the route. The main time loss comes from the in-game dialogues and roleplay cutscenes that cannot be skipped.

Farming on Multiple Alts

With a ~1% drop chance, one attempt per week on a single character is an extremely slow method. To increase your chances:

• Create several level 80 alts (10 alts = 10 attempts per week, ~10% cumulative chance)
• Each alt should clear the raid on its own — a full raid clear takes 5-10 minutes
• Best classes for a fast clear: Demon Hunter (high mobility), Druid (movement speed in Cat Form), Warrior (Heroic Leap for fast movement)

The Glider Skip (All Classes)

To skip Valithria Dreamwalker and speed up the route through the upper wings, you can use a combination of items:

1. Any item with a slow fall effect
2. A glider toy (for example, the "Stylish Black Parasol")

Activate both effects and glide past Valithria's room directly to Sindragosa, saving 1-2 minutes on every run.
