Vexhul and Ithraz are a two-boss cleave fight ruled by Eternal Venom: most mechanics stack it, reaching the cap kills you on Heroic and Mythic but only stuns you on Raid Finder and Normal, and the ONLY cleanser is deliberately soaking Ithraz's Ravenous Feast. The raid manages stacks like a currency while keeping both serpents' health even, because a death hands the survivor stacking Uncoiled Wrath.
Watch your Eternal Venom counter like a health bar. Heroic kills you at 10 stacks. Mythic kills you at 11. Raid Finder and Normal cap at 11 too, but stun you instead of killing you. Feast soaks are the only way down. Never volunteer for a mechanic at high stacks.
Ravenous Feast strikes three times as a split-soak circle with knockback. The three assigned groups take one strike each, brace for the push, and bank the stack removal. Mythic needs four bodies in every strike; the other three tiers need one.
The Vexhul tank fights the Caustic Deluge channel pushback; everyone dodges the Spawn of Vexhul's spinning toxic beam, kills the adds, and one assigned player soaks each Caustic Globule before its 10 second fuse venoms the whole raid.
The Ithraz tank eats three Stone Breaker slams - every slam must hit a player - then swaps for 1.5 minutes of amplified Stone Breaker damage. Coiling Ichor players pulse damage to those nearby, so they run to the edge and drop their puddle in a safe lane.
Nuke the Blood Mass add that spawns after each Feast soak, dodge Sanguine Storm swirlies and the slime waves rolling off the platform backs, and keep two-target cleave rolling with even health.
At 2:30, and again at 5:30 and 8:00 if the pull runs that long, both serpents Submerge and rain venom that fills one platform section for good. Vexhul then channels Vile Flood, a 14 second toxin beam that sweeps a frontal arc - the orbs around her spin the way it will travel, so read them and rotate ahead of it. Ithraz relocates to a new edge spot (one tank runs within range so Clotted Bolt never fires) and rains Sanguine Storm gore. Then Phase 1 repeats on a smaller platform.
The written plan is maintained separately from the changing video feed. Check current hotfixes and follow your raid leader's marked wall and cooldown assignments.
The stacking nature DoT that everything applies. What the cap does to you depends on your difficulty, and only Feast soaks remove stacks.
Wipe condition: On Heroic and Mythic a player at cap dies instantly and, on Mythic, leaves a Globule where they fell. On Raid Finder and Normal the cap is a huge hit and an 8 second stun instead.
Split-soak all three rapid strikes with the assigned groups, brace the knockback, and treat the removed stack as the reward.
Wipe condition: A missed strike is heavy raid damage AND the raid keeps its venom stacks - the fight's economy collapses.
Each slam must hit a player: the assigned tank takes three, then swaps out for 1.5 minutes while amplified.
Wipe condition: An empty slam is raid-wide damage and a knockback; a fourth slam on the same tank is usually fatal.
Tank into the pushback; one player soaks each Globule inside 10 seconds.
Wipe condition: An unsoaked Globule applies Eternal Venom to every player in the raid at once.
Run to the edge while pulsing damage to those nearby, get single-target healing, and drop the expiry puddle in a planned safe lane.
Wipe condition: Ichor walked through the raid or dropped mid-platform poisons the shrinking play space.
Keep both serpents' health even to the very end.
Wipe condition: The surviving serpent gains stacking increased damage every 3 seconds - a staggered kill becomes a wipe timer.
The stacking nature DoT most mechanics apply. The cap, and what it does to you, changes with your difficulty.
Response: Budget your stacks and clear them at every Feast.
Ithraz lances his current target with gore when that target is out of his range.
Response: Tanks stay in range through every reposition, including intermission relocations.
Both serpents fill the air with fumes. Passive raid-wide damage all fight.
Response: Healers pace throughput; there is no downtime to bank.
Vexhul funnels toxin into her target for 5 seconds, splashing acid that leaves Caustic Globules.
Response: Pre-position against the push and rotate cooldowns through the channel.
Explodes after 10 seconds, applying Eternal Venom to all players - unless one player soaks it first.
Response: Assigned low-stack players soak each Globule deliberately.
Summons Spawn of Vexhul that spew a spinning toxic beam around the arena. The call itself venoms the raid.
Response: Kill the adds fast and move with the beam, never through it - and do not move erratically if its beam targets you.
A 6 second churn that damages everyone and forms waves pathing across the arena.
Response: Sidestep the wave lanes as they cross.
Three rapid split-soak strikes with knockback. Each soak eats one Venom stack and leaves you Feasted, which blocks the next one.
Response: Three groups, one strike each, so nobody wastes a strike while Feasted.
Debuffed players pulse damage to those nearby and drop a puddle on expiry.
Response: Run out, take spot heals, place the puddle at the planned edge.
Pushes players away then slams repeatedly; each slam must hit a player, and hit players take 33 percent increased Stone Breaker damage for 1.5 minutes.
Response: The assigned tank soaks three in a row, then swaps; immunities can cheat individual slams.
Both serpents submerge and rain venom, filling one platform section for the rest of the fight. Vexhul's Vile Flood then sweeps a frontal toxin beam for 14 seconds.
Response: Read the orb spin for the beam direction, shift to the new clean area by Ithraz, and dodge the frontal channel.
Ithraz showers the platform with gore for 18 seconds; each impact hits everyone within 4 yards.
Response: Dodge the impacts while you read the orbs for Vexhul's beam direction.
Swap after every third Stone Breaker slam, fight the Deluge pushback with your back to open ground, and sprint to Ithraz's new intermission position so the range nuke never fires.
Cooldown every Feast soak window, single-target the Coiling Ichor carriers, and watch venom counters - a player two stacks off their tier's cap is a triage priority, not a note for later.
Two-target cleave with the health bars locked together, hard-swap to the Blood Mass after each Feast, and volunteer for Globule soaks only at low venom stacks.
Your venom count decides what you may soak, and your difficulty decides the cap. Say it out loud when assignments are called, and remember each intermission permanently shrinks the platform - sloppy puddle placement compounds.
