Ula'tek's Hall of Fame Closed With the 12.1.5 Reset — and the Numbers Say the Tier's Real Wall Was Never Ula'tek
The race for The Venomous Abyss is officially over. Community manager Linxy confirmed on October 12 that the Hall of Fame was full, and it closed for new entries with the weekly resets that also carried patch 12.1.5: October 13 in the Americas, October 14 in Europe. The first 200 guilds to kill Mythic Ula'tek keep the Hall of Fame: Ula'tek achievement and the "Famed Slayer of Ula'tek" title; from the reset onward, neither can be earned again.
What makes the timing worth writing about is what arrived in the same window: the largest tuning pass the tier has received, landing after the title race ended and alongside the mid-season patch.

The numbers behind the closing
Progression tracking makes the shape of this tier unusually legible. As of the Hall of Fame announcement, roughly 1,020 guilds had killed Mythic The Twin Fangs — and only around 263 had killed Mythic The Coiled Altar, the penultimate encounter. That is a drop of about three-quarters at a single boss, and it is not where the difficulty curve is supposed to bend.
It is also the second tier in a row with this exact profile. In Liberation of Undermine, Mythic Mug'zee — not Gallywix — was the boss that decided who finished. The end boss has become a victory lap; the mid-tier side-pair is the wall. Our October 6 nerf piece documented raiders making that argument about Ula'tek specifically, and the progression data now backs them up: Blizzard answered the complaint about the wrong boss by nerfing the right one a week later.
For context on what that last window was worth: Hall of Fame entries are a strict count, so a guild killing Mythic Ula'tek in the final hours was racing against the reset rather than against the boss. European groups had a little under two days from the announcement; North American groups had under one.
The tuning that landed with the patch
Blizzard's October 13 dungeon and raid tuning post went live with 12.1.5, and the raid half targets the Coiled Altar directly:
| Change | Where |
|---|---|
| Toxic Deluge Phase 1 orbs: 10 → 8 | The Coiled Altar, Mythic |
| Virulent Mutations in Phase 1: 5 → 4 | The Coiled Altar, Mythic |
| Mutation and Mutagenic Venom radius: 8 → 6 yards | The Coiled Altar, Mythic |
| Dreadmarch targets: 4 → 3 players | The Coiled Altar, Mythic |
| Manifestations of Dread show their red glow immediately on fixate | All difficulties |
| A dead fixate target now despawns the Manifestation instead of re-fixating | All difficulties |
| Detect-and-stun angle widened by 10 degrees | All difficulties |
| Eternal Nightfall cast time +2 seconds | All difficulties |
| Sszorak reaches 100 rage 5 seconds slower | Mythic |
The dungeon half is broader still, touching Altar of Fangs, Murder Row, Ruby Life Pools, Temple of Sethraliss, The Blinding Vale and Voidscar Arena. Altar of Fangs alone received reductions across ten different enemies, headlined by Living Venom at −25% health and −50% Venom Burst damage. Ruby Life Pools' Defier Draghar lost 27% of his health, Primalist Cinderweaver's Living Bomb is now dispellable without detonating, and Murder Row's Zaen Bladesorrow had Fire Bomb damage cut by a third.
Read together with the Ula'tek hotfixes of October 6 — Spectral Coils −20%, Mythic Toxic Burn −30%, Caustic Waves cut from seven waves to three — the pattern is coherent: Blizzard is dismantling this tier's difficulty spikes in the same fortnight it is asking players to push for a 3,600 Keystone Myth rating.
Why the order of operations matters
Nerfing a raid after its Hall of Fame closes is not accidental generosity; it is the standard modern cadence. The title protects the race's integrity at the top, and the tuning that follows opens the tier to the guilds who were never going to make the top 200 anyway.
What gives this pass extra weight is the calendar around it. The week of October 20 brings Ascendant Venomstones and the removal of the Season 2 crest cap, and 12.1.5 has already added the Kith'ix raid, the Labyrinth of Kindo'jan and the Aqir Invasions on top of the existing instance. A guild stalled on the Coiled Altar now has an easier wall, more power, and one more raid to split its raid nights between — which is roughly the point.
The open question is whether Kith'ix gets a Hall of Fame of its own. Blizzard has not said, and the flexible 15–25 player Mythic format makes a traditional 200-guild count awkward to define. Until it does, the Venomous Abyss plaque is the only one this season.
Day-one rough edges
Worth noting alongside the tuning: 12.1.5's first day also produced hotfixes of its own. The second boss of Murder Row was found to be dealing no real damage and was corrected, and players reported melee swings displaying "phantom damage" on health bars in Midnight — a display bug rather than a tuning problem. Neither is a reason to delay a key night, but both are worth knowing before you read your team's logs and panic.
