Overview
Eternal Venom is the whole encounter. Soak Ravenous Feast to strip one stack per hit. Each hit applies Feasted and knocks you back, so the same player cannot soak twice. Use three assigned groups, one soak each. That knock drops Tainted Blood. The group that just soaked has eight seconds to soak those puddles.
They Submerge after two main-phase cycles. The third Submerge is the practical enrage: the floor is gone, and Uncoiled Wrath will have already started if the health bars diverged. They cannot be moved, so spread loosely around both. Lust on pull. Keep them within a few percent and kill them in the same window. Dying with Eternal Venom spawns extra globules, so a messy death snowballs the soak plan.
Vexhul
Caustic Deluge is a tank pushback beam. The tank must stay in range while globules spawn. Low-stack players soak those orbs, one at a time. Dying with Eternal Venom spawns extra globules. Those globules gain Barbed Bulwark and must be interrupted before they are soakable. Rouse the Brood adds spawn on the bosses and need assigned interrupts. Venomous Emergence plants three Spawn of Vexhul in the middle. They pulse a stack on spawn and cast Corrosive Spit beams. Plant after a one-second adjust so the raid can sidestep. Stir the Depths sends slow waves across the floor. Each hit is another stack. Tanks never leave melee, even when adds are up.
Ithraz
Stone Breaker knocks the tank and drops three sequential soaks. Eat all three in spawn order or the platform slams the raid, then taunt-swap. Coiling Ichor players walk to the rim. The circle shrinks, so you can tighten drops as it expires. Ravenous Feast is three split soaks. Each hit strips one Eternal Venom, applies Feasted, knocks, and drops Tainted Blood that the knocked group has eight seconds to soak. Use three assigned groups, one feast each. Eternal Venom kills at 9 stacks, so call high-stack players into the next feast.
Submerge
Both snakes dive. Orbs around Vexhul telegraph which way Vile Flood will rotate. The beam always starts on Vexhul's tank, so the raid can skip it by moving the other way. Ithraz rains Sanguine Storm while you circle. Congealed Gore pools snare 60%, so walking into your own Ichor drops during the beam is how people die. After three phases you are out of floor.
By role
Tanks
Stay in melee on both, even during adds. Soak every Stone Breaker in order, then swap. On Caustic Deluge, stay in range while globules spawn.
Healers
Eternal Venom ticks harder as stacks climb, so put extra healing on loaded players. Ramp each Ravenous Feast soak and the Tainted Blood that drop after the knock. Toxic Fumes is constant chip under the big overlaps.
DPS
Interrupt globules behind Barbed Bulwark. Interrupt Rouse the Brood. Kill Venomous Emergence spawn first. Dodge waves. Cleave both so they die together before the third Submerge.
Why pulls die
People die to Eternal Venom at 9 stacks, to a second Ravenous Feast soak while Feasted, or to Tainted Blood left on the floor. Deaths spawn extra globules behind Barbed Bulwark. Stone Breaker hitting nobody slams everyone. Unkicked Rouse the Brood adds stall the bosses. Vile Flood plus Sanguine Storm is the largest overlap, especially through Congealed Gore snares. Late deaths are Uncoiled Wrath after one snake died first.
Questions
How do you remove Eternal Venom?
Stand in one Ravenous Feast hit. Each strike removes one stack of Eternal Venom, applies Feasted, and knocks you back, so the same player cannot soak twice. Use three assigned groups. After the knock, that group soaks Tainted Blood within eight seconds.
Should you kill one Twin Fang first?
No. They do not share health. The survivor gains Uncoiled Wrath and ramps. Kill them together, and finish both before the third Submerge.
Which way do you run during Submerge?
Read Vexhul's rotating orbs, then move opposite the Vexhul tank. The beam starts on that tank. Going the other way skips the first sweep. Do not walk into Congealed Gore from your own Ichor drops.
What happens if someone dies with Eternal Venom?
Dying with Eternal Venom spawns extra globules. Those globules gain Barbed Bulwark and must be interrupted before they are soakable. Rouse the Brood adds on the bosses also need assigned interrupts.
