Wrath of the Lich King · Tier 8 · Ulduar
Ulduar raid guide
14 boss-specific tactics, progression checklists and a documented change history from the original Wrath to Wrath Classic.
How to use this guide
Read the raid change history and the boss TL; DR before the detailed steps. Each card separates mandatory core tactics, role responsibilities and hard/heroic mechanics that change depending on the version.
The target version is level 80 Wrath. Classic level 60, Timewalking and the legacy scaling of later expansions do not change the tactics of this guide.
Ulduar in chronological Wrath progression
Ulduar's 14 bosses are connected by vehicles, branching progression and hard modes activated within the encounter. The guide explains normal and hard mode solutions in the same boss card.

Ulduar: nerf and change history
The timeline separates intentional difficulty changes, release schedule, loot/catch-up changes, and actual bug fixes. Inaccurate pre/post figures are not filled with guesswork.
| Date | Documented change | Effect |
|---|---|---|
| Patch 3.1 / 14/04/2009 | Ulduar was released as a raid with 14 bosses. | Hard modes were activated with encounter functions, not with a separate difficulty menu. |
| Patches 3.1.1 to 3.1.3 | Several encounters were adjusted: among others, XT, Hodir, Mimiron, Vezax and Yogg received fixes and nerfs. | Nerf history is boss specific and not one raid buff. |
| Wrath Classic 2023 | Ulduar was released with a strong pre-nerf base and increased item levels; XT hard mode health reduced while keeping the six minute berserk. | The Classic change is not the same as the end state of 2009. |
| Wrath Classic 2024 | The Val'anyr fragments drop was increased as an end-of-season catch-up. | The loot change did not change the combat difficulty of the encounter. |
The boss card nerf sections use this raid level timeline and only raise differences relevant to the encounter.
