Hotfixes August 25: Nymrissa, Ula’tek, and M+ Get a Reset Pass
Weekly maintenance ships Tidebound Grotto and Venomous Abyss nerfs, a wide Mythic+ tuning pass, and the scheduled Season 2 class changes.
August 25 maintenance wasn’t only the class tuning pass. Blizzard also leaned on Lairs, the raid, and the Season 2 key pool after a brutal first week.
Tidebound Grotto
Nymrissa Wavecaller takes another cut after groups struggled on Mythic:
- Boss health −5% Heroic / −10% Mythic
- Abyssal Rain initial −12.5%; periodic −12% Heroic / −20% Mythic, plus weaker large-group scaling
- Frost Burst −40%; Shatter delayed 30s → 40s
- Shorter Chilling Frost; 2 Bubblefin Frostscales per murloc wave (was 3)
Venomous Abyss
The zone and several bosses get breathing room:
- Fewer trash spawns, less blood to open doors, Venom Withdrawal damage −30% / duration −50%, Serpent Wards health −75%
- Vashnik — fewer Malignant Totems, spawn tweaks, Imbibe overdamage fixed on Normal/Heroic, achievement/grip bugs
- Coiled Altar — Malacrass phase 3 health −10% and Veil of Twilight absorb −15% on Normal/Heroic; Sever aura duration fix
- Ula’tek — easier Serpent’s Bite soaks, longer Greasy Hatchling (20s → 35s), venom-pool spit protection, Heart targeting, wipe-reset, and a stray Stone Venom stack removed
Mythic+
Notable dungeon beats: Blinding Vale count 655 → 686 with a thinner last area; Potatoad Matriarch count value doubled, HP −10%, Toxic Spew −50%; Altar of Fangs loses a High Evolutionist after Rav’i; pack/routing tweaks in Den of Nalorakk, Ruby Life Pools, Temple of Sethraliss, Murder Row, and Kings’ Rest.
Class PvE/PvP numbers from the Aug 25 tuning post are in the same hotfix list. NA reset details: weekly reset live.
