The Twin Fangs Raid Guide (The Venomous Abyss)

Overview

• One debuff decides this fight: Eternal Venom. Almost every green effect adds a permanent stack, and on Heroic and Mythic ten stacks kill you outright.
• The only way to shed stacks is soaking Ravenous Feast, so every player's job is to avoid stacks they do not have to take.
• The two serpents, Vexhul and Ithraz, have separate health pools and cannot be moved. Kill them at nearly the same time.
• Tanks trade serpents around two ramping tank mechanics; healers deal with constant raid damage that gets worse as stacks build.

The Twin Fangs

Abilities

• Eternal Venom: a permanent stacking damage over time effect applied by most of the fight's mechanics. It never falls off on its own.
• Ravenous Feast: Ithraz strikes three times in quick succession, splitting heavy damage between everyone in each circle. Each soaker loses one Eternal Venom stack, and soakers are left with a short debuff that makes another Feast hit extremely dangerous.
• Caustic Deluge: Vexhul channels into her tank, pushing them back while acid splashes land nearby and form globules.
• Envenomed: the stacking Deluge damage increase on Vexhul's tank. Its long duration is why the tanks trade bosses.
• Caustic Globule: the globules left by the Deluge. One player soaking each one takes a single stack; if one ruptures untouched, the entire raid gets a stack.
• Stone Breaker: Ithraz roars to push players away, then slams three spots in sequence. Each slam must hit someone (normally the tank) or the whole raid takes a big hit and a knockback.
• Venomous Emergence: raid-wide damage that gives everyone one unavoidable stack and summons three Spawn of Vexhul in the middle.
• Corrosive Spit: the spawns aim line attacks at players. Anyone in the line gains a stack.
• Stir the Depths: raid-wide damage while venom waves roll across the platform. The waves add stacks; the pulse itself does not.
• Concentrated Spittle: punishes Vexhul's tank for leaving her reach. Stay in range and it never happens.
• Vile Flood: during the Submerge intermission, Vexhul sweeps a huge rotating beam across the platform. Standing in it stacks venom fast enough to kill.
• Sanguine Storm: at the same time, Ithraz rains gore impacts that leave short slowing pools.

Two more mechanics have no page in our database yet: Coiling Ichor marks players with shrinking circles that leave long-lasting slow pools when they expire, and Uncoiled Wrath gives the surviving serpent a rapidly stacking damage increase once its twin dies.

Phases

The bosses run a fixed rotation twice: Caustic Deluge, Stone Breaker, Venomous Emergence, Coiling Ichor, Stir the Depths, then Ravenous Feast. After the second Feast they reach full energy and Submerge, showering venom that leaves damaging slicks, then resurface for the Vile Flood and Sanguine Storm combination before the loop starts again. The fight hard enrages at a later Submerge, so both serpents must be dead before then.

Tank

• Each tank holds one serpent. Vexhul's tank stays in her reach during Caustic Deluge while being shoved back.
• Ithraz's tank runs back in after the Stone Breaker roar and stands in the three slams in order. Watch which swirl appears first and follow the sequence.
• Because both Envenomed and the Stone Breaker debuff last a long time, swap serpents between sets rather than taunting back and forth.

Healer

• Toxic Fumes deals raid-wide damage every couple of seconds for the whole fight, and the permanent Eternal Venom ticks add to it as stacks build.
• Track stack counts on raid frames. Globules should go to players with low stacks, so steer anyone near the limit away from them.

DPS

• Kill the three Spawn of Vexhul quickly; every spit they get off is another potential stack.
• If you are targeted by Corrosive Spit, settle into position and point the line away from people.
• Players with low stacks take Caustic Globules, one per globule. Do not grab two by accident.
• Cleave both serpents and keep their health close. A large gap at the end lets Uncoiled Wrath ramp out of control.
• Bloodlust on the pull.

Ravenous Feast assignments

Plan three soak groups, one per strike, decided before the pull. Each player can only lose one stack per Feast no matter how many strikes they stand in, and a second hit while debuffed is deadly. Method notes an alternative of two groups plus immunities for the third strike, and immune soakers still get their stack removed.

Difficulty notes

• Normal plays the same rotation with more forgiveness.
• Heroic makes ten Eternal Venom stacks lethal and makes the Feast debuff block a second soak.
• Mythic adds a lot: dying with Eternal Venom drops extra globules (Method says three), Ithraz's Blood Torrent shields globules with Barbed Bulwark that must be broken with crowd control before soaking, Rouse the Brood spawns Broodlings (ten, per a September 15, 2026 Blizzard hotfix) whose raid-damage cast must be interrupted, and each Feast strike needs a minimum number of soakers and leaves Tainted Blood founts that have to be soaked within a few seconds. Method recommends splitting the raid into left, right and melee groups from the pull.

Loot highlights

Items from this encounter's loot table in our journal data:

• Vexhul's Everflowing Gland: Intellect trinket with an on-use Nature damage effect.
• Preternatural Antivenom: Critical Strike trinket whose effect triggers from your healing, so it is aimed at healers.
• Ravenous Feaster's Fang: one-hand Agility weapon with Mastery and Critical Strike.
• Amulet of the Twin Fangs: neck with Mastery and Haste.
• Venomforged Effigy, Venomcured Effigy, Venomcast Effigy and Venomwoven Effigy: tier tokens that each create a set head item for the matching classes.
• Pattern: Adorned Fang: a crafting recipe for profession players.

Common mistakes

• Clipping a Corrosive Spit line or a Stir the Depths wave and burning your stack budget early.
• Letting a Caustic Globule pop unsoaked, which gives all twenty players a stack.
• Two Feast groups standing in the same strike.
• Running with the Vile Flood beam instead of crossing it early.
• Killing one serpent well ahead of the other.
