The Venomous Abyss is the main raid of WoW Midnight Season 2, arriving in Patch 12.1: Curse of Ula’tek. This Heroic PTR guide focuses on Nek’zali the Soulcoiler and Entombed Sentinels, two early encounters in the Temple of Ula’tek, with an additional journal-based preview of the final boss, Ula’tek.
Since this is PTR content, names, numbers, tuning, and encounter pacing can still change before launch. Strict linear boss order is also not fully settled across public PTR sources, so the roster should be treated as raid context rather than a confirmed kill sequence.
In this guide, we’ll cover:
- How Nek’zali’s Soulcoil Well, Raised Amani adds, Possession Barrage, and Ritual of Awakening intermission work
- How to handle Entombed Sentinels on Heroic, including boss spacing, Helical Toxins, Blood Venom pools, and Venom Coagulation
- Role priorities for tanks, healers, and DPS on both covered Heroic encounters
- A journal-based Ula’tek final boss preview, including her three-stage structure, egg mechanics, Doomscale adds, and final platform pressure
- The current Venomous Abyss PTR roster, including the Bargained Crown / Coiled Altar naming conflict
- Season 2 gearing changes, Bonus Rolls, Ascendant Venomstones, Catalyst updates, tier tokens, notable loot, and achievements

| Encounter | Notes |
| Nek’zali the Soulcoiler | Soulcoil Well encounter |
| Vashnik the Malignant | Grouped with Nek’zali in the Essence of Ula’tek wing achievement |
| Entombed Sentinels | Breath & Blood of Ula’tek |
| The Lost Explorers / Mor’zahi | Possessed tortollan encounter |
| Sszorak | Venom beast encounter |
| The Twin Fangs | Vexhul & Ithraz |
| The Bargained Crown / The Coiled Altar | PTR naming conflict — raid achievements use “Bargained Crown,” the zone page uses “Coiled Altar” with placeholder Zul’jan/Malacrass text |
| Ula’tek | Final boss, not PTR-tested |
If you want to prepare for The Venomous Abyss rewards without waiting on progression groups, you can pre-order a Venomous Abyss Normal Boost, Venomous Abyss Heroic Boost, or Venomous Abyss Mythic Boost, depending on your target difficulty. Normal is the safer entry point for 285–298 ilvl rewards and decorations, Heroic is the main path toward 298–311 ilvl gear, and Ahead of the Curve, while Mythic is aimed at 311–337 ilvl equipment, Cutting Edge, and the highest-end raid rewards.

Boss 1: Nek’zali the Soulcoiler

Less about boss uptime, more about keeping the Soulcoil Well under control — every spirit that reaches it feeds Nek’zali’s energy. At full energy, she enters Uncoiling, gaining Uncoiled Rage: 150% faster attacks/movement, 500% more damage, and taunt immunity. This is a soft enrage, not a timer — treat add control as the priority over boss damage through most of Phase 1.
Adds: Raised Amani climb from sarcophagi and beeline for the well, shielded by Gravebound Advance (a 25%-max-health magic absorb that grants death immunity while it holds). Slow or root them, burn the shield, then kill — don’t park them in CC forever, they need to actually die before reaching the well. Killing one too close to the well risks Corpse Blight (AoE burst + DoT), so don’t stack on the corpse. Latent Cultists spawn from a separate mechanic and orbit the well, hitting nearby players with Shadow damage and a slow — cleanup priority, not a chase target.
Tanks: Nek’zali’s melee, Sever, applies stacking Hollowed (Shadow DoT, cuts healing/absorbs 5% per stack) — swap before stacks overwhelm healers, not on a flat timer. Possession Barrage sends spectral echoes toward her current target that do less damage the further they travel, so tanks want distance from the raid; on Heroic each connecting echo also adds a Hollowed stack. Healers should hold externals for whichever tank is stacking Hollowed while also eating an add pickup.
Movement: PTR testing shows pull effects and rotating floor hazards layered onto add control. Mobile classes (Blink, Shimmer) dodge the pull easily; everyone else walks against it. The hazards are mostly personal responsibility — don’t tunnel on adds hard enough to miss the floor moving.
Intermission — Ritual of Awakening: At 50% health, Summoner Jawae raises Tethers of Awakening. Kill the Echoes of Jawae to sever them and bring her back. Heroic adds Hungering Pyre (shared soak around the Echoes — spread, don’t dogpile) and Cremation, which detonates near corpses, so stay off the Raised Amani bodies. Stand in the safe zones during the transition; standing outside can kill quickly.
Most groups will use Bloodlust/Heroism after the intermission; if Uncoiling tuning proves severe, saving it for the final burn may be the better call.
PTR notes: Nameplate clutter from this many adds is real — a filter addon separating delayed/low-priority adds from live targets helps. Ground-targeted spells can have pathing issues at the well’s dead center; aim slightly off-center.
Boss 2: Entombed Sentinels

Two golems fought simultaneously: Breath of Ula’tek (venom/acid, “green”) and Blood of Ula’tek (blood, “red”). Two tanks, two parallel mechanic sets, plus a shared math puzzle.
Positioning: Within 25 yards of each other, the Sentinels gain Ula’tek’s Dominance — 99% reduced damage taken. Keep a hard 25+ yard buffer; don’t drag them together for cleave, it just wastes raid damage. Each also applies its own 40-yard aura (Mark of Acid / Mark of Blood, stacking every 6 seconds) — the real danger is sitting in both auras at once, not proximity to one boss.
Breath: sprays Toxic Droplets in front of itself — step on them to clear safely, or they erupt into raid-wide Noxious Blast. Assign droplet duty; tanks should mind facing. Heroic adds Living Venom, a projectile that returns toward Breath after ~4 seconds — stay out of the return path.
Blood: applies Blighted Blood; undispelled, it becomes Blood Venom, leaving a toxic pool on expiry (bigger infections, bigger pools) — clean, prompt dispels matter. Unstable Miasma marks a player, detonates after 8 seconds splitting Shadow damage within 5 yards, then spreads the resulting Blood Venom via Clinging Murk — more soakers means smaller individual puddles.
Tanks: swap Breath around Empowering Slam (15% Physical damage ramp per same-target hit) and Blood around Bloodvenom Injection (heavy hit + 40-second stacking Shadow DoT); route pool placement away from raid movement lanes.
Helical Toxins is the signature puzzle: lands on multiple players, needs exactly 4 stacks — colliding with another affected player combines counts. Pair as 2+2 or 1+3. Miss the number and it expires into Cultivated Burst (heavy Plague hit + long DoT) — simple on paper, punishing for tunnel vision.
Venom Coagulation (a Breath-spawned add) casts Contaminate, raid-wide Nature damage on a tick until killed — always top DPS priority. Some PTR footage suggests the Sentinels reposition after Vitriolic Stasis (confirmed: 99% damage reduction, heals the weaker boss to match) — treat as an observed pattern, not a locked mechanic, and keep tank assignments ready to re-establish.
Roles: Tanks keep distance and manage swaps/pools; healers dispel Blighted Blood fast and save cooldowns for Contaminate/intermission; DPS hard-swap to Venom Coagulation, track their own Helical Toxins stack, avoid Living Venom’s return path.
Venomous Abyss Loot and Gearing Changes

- Bonus Rolls are a direct Great Vault option from season start (not a Week-8 unlock like Season 1). Starting Week 8, Orin Straylight near the Catalyst in Silvermoon City also grants one weekly bonus roll.
- Bonus-rolling a raid boss now costs 1 token instead of 2.
- LFR/Normal/Heroic Vault and bonus-roll rewards jump to the first step of the next upgrade track; Heroic gives Myth 1/6, Mythic gives Myth 6/6.
- The top item levels (Myth 9/6) are reserved for Very Rare items and the final two bosses’ drops.
- Ascendant Venomstones replace Voidcores as the upgrade currency for maxed Hero/Myth gear, now also covering necklaces alongside weapons and trinkets.
- Catalyst conversions keep the donor item’s secondary stats and cantrip effects.
- Crest costs: scaling costs (each rank pricier than the last) briefly returned on an early PTR build — a maxed Heroic trinket would’ve cost 150 crests instead of 100 — before a later PTR update reverted to the flat 20-per-rank system live servers use now. The standard system looks likely to carry into Season 2.
Patch 12.1 also adds Altar of Fangs, a three-boss dungeon joining the Season 2 Mythic+ rotation; datamined maps may still be incomplete before launch.
How testing works: Blizzard runs scheduled PTR raid tests with dedicated feedback threads for each encounter. Test characters are scaled to the appropriate level and gear, with profession, class set, PvP, and trinket vendors available in major cities. Nexus-Lord Donjon Rade teleports players into the raid while testing is active. These sessions are for bug reports and tuning, so schedules, bosses, and numbers can change between PTR builds.
If you only need a specific drop, achievement, or tier slot, a Venomous Abyss Single Bosses boost is the cleanest option. It lets you target selected raid bosses instead of booking a full clear, which is especially useful for chasing 285–337 ilvl rewards, unique achievements, or specific loot from bosses like Entombed Sentinels, Vashnik, Sszorak, The Twin Fangs, or Ula’tek.
Boss 8: Ula’tek (Final Boss)

A five-headed snakeoid beast — a serpent goddess imprisoned 16,000+ years, now breaking free. This section comes from a complete datamined encounter journal, but Ula’tek is not available for PTR raid testing: mechanic names are confirmed, numbers and pacing are not. Three stages, two intermissions.
Stage 1 — Fury of the Serpent Mother: Caustic Wingfall sends venom waves that hit on impact, tick for 10 seconds, and stack — and instantly hatch any Devourer’s Spawn (eggs) they touch. Call of the Serpent drops more eggs from the ceiling; carried eggs tick Nature damage via Malignant Shell (Mythic: Hardened, immovable + absorbs a hit, plus Noxious Shell, which cross-hatches nearby carriers). Destroyed eggs burst into raid-wide Putrid Membrane. Eggs hatch into Venomous Birthling (Heroic+: Poisonous Bite) or Blightscale Viper (Acidic Burst; Heroic+ also Petrifying Sting, stone-locking anyone within 10 yards).
Tanks manage Mother’s Wrath/Unchecked Rage (stacking Stone Venom slow/DoT — both hit the whole raid if she can’t reach melee). Gore Rattle rotates between a platform slam, a knockback sweep, and Shattering Coil (damage reduced by nearby player count — stack up for this one). Rage of the Shackled exposes her Venomous Heart to +100% damage for 20 seconds — the Stage 1 burn window. Necrotic Vapors ticks constant raid damage throughout.
Intermission — Incubating Malice: Toxic Incubation lines the nearest player and insta-hatches crossed eggs; Gore Rattle and Necrotic Vapors continue.
Stage 2 — Children of the Doomscale: Doomscale Wardens cast interruptible Malice, reposition via Shadow Molt, and grow Slithering Clutch eggs via Writhing Gestation; Heroic+ adds Grasping Fangs (45-yard root, 8 seconds). Dead Wardens leave a Doomscale Pheromones puddle — don’t kill them in the stack. A disturbed egg can spawn a Ravenous Doomscale; disrupting its gestation doubles damage taken (Defect: Weakened) but triggers a raid-wide stun (Dread Roar) — time it.
Intermission — The Shattering: brief, just continued Shattering Coil and Necrotic Vapors.
Stage 3 — Ula’tek’s Ascension: Stage 1 mechanics continue, plus Serpent’s Bite (applies Surging Fang, which turns the target to Calcified Corpse if not leeched within 15 seconds; leeching applies Volatile Purge, which erupts on nearby players at expiry — spread out before leeching). Venom Bubbles knock back on contact. Demolish destroys part of the platform — the “shrinking room” mechanic. Fury Unleashed is a major raid-wide hit plus DoT — treat as a cooldown trigger. Ula’tek’s Bond means all her parts share one health pool throughout.
Roles: Tanks manage Stone Venom and stay in range to avoid raid-wide tank-mechanic spillover. Healers plan around constant Necrotic Vapors drain plus Rage of the Shackled/Fury Unleashed/Putrid Membrane bursts. DPS prioritize Blightscale Vipers and disrupted Doomscales, keep eggs off venom, and burn during Exposed Heart.
Notable loot: Slumbering Coil Curio, Jaw of the Shackled Goddess, Abyssal Broodfiend’s Bardiche, Font of Venomous Rage, Voracious Heart of Ula’tek, Caustic Repose Greatbow, Aqirbane Reliquary, Venomkeeper’s Horrific Cowl, Gaze of the Coiled Watcher, Awoken Dreadfang Cuirass, Chausses of Unbound Rancor, Zatha’tek Breath of Corruption, Jan’thrazet the Soul Fang, and Primeval Skyfriend (Mythic-only mount). Heroic/Mythic kills also grant trophy items.
Ula’tek is the main prestige target of the raid, with final-boss loot, Ahead of the Curve, Cutting Edge, and Mythic-only rewards tied to her kill. If your goal is the final boss specifically, consider our WoW Ula’Tek boost; if you are chasing the Mythic-only Primeval Skyfriend flying mount, use the Primeval Skyfriend boost instead. For achievement collectors, the Glory of the Venomous Abyss Raider Boost / Crimson Venomfang boost is the best bet.
Rewards and Tier Sets

Tier tokens drop across the roster: Entombed Sentinels (Gloves), Vashnik (Chest), Lost Explorers (Shoulders), Sszorak (Legs), Twin Fangs (Helm). Ula’tek’s class-token mechanic isn’t confirmed yet, but she drops the Slumbering Coil Curio and the notable-loot list above. The Midnight Catalyst still converts gear into a missing tier slot if needed.
