Midnight Season 2 encounter guide

The Twin Fangs

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.

Before the pull

Set the encounter assignments before pull

  • Special notes: Stone Breaker soaks can be immuned, there are no dispels and no interrupts.
  • Split the raid into three groups for Ravenous Feast - it strikes three times in quick succession as a split-soak circle with a knockback, and each soak removes one Eternal Venom stack.
  • Set the tank plan: the Ithraz tank soaks three Stone Breaker slams, then swaps; the Vexhul tank fights the Caustic Deluge pushback.
  • Talent for sustained two-target cleave and agree on keeping boss health even - Uncoiled Wrath gives the surviving serpent stacking increased damage every 3 seconds: 10 percent on Raid Finder and Normal, 25 on Heroic, 30 on Mythic.
  • Assign Coiling Ichor drop spots at the platform edges. The first intermission is fixed at 2:30 and permanently slimes a section of the platform; later ones follow at 5:30 and 8:00, which only a slower pull will ever see (the slowest top-50 Heroic kill ends at 5:12).
Fight flow

Resolve the encounter in this order

  1. 01

    Track your venom

    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.

  2. 02

    Soak the Feast in threes

    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.

  3. 03

    Handle Vexhul's side

    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.

  4. 04

    Handle Ithraz's side

    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.

  5. 05

    Kill the Blood Mass, dodge everything

    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.

  6. 06

    Survive each intermission

    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.

Measured timeline

What the clock actually does

Fixed timer - same clock for every raidTop-50 Heroic kills run 4:29 to 5:12, median 5:05.

A fixed clock, on a narrower base of evidence than the other timed fights here. The intermission landed at exactly 2:30 in all five sampled kills and the three repeating mechanics share one cadence of about 68 seconds, but those kills span only 43 seconds and no substantially slower kill was available to test against. Treat 2:30 as reliable and the 68 second cadence as strong; if your pull runs much longer than five minutes, verify rather than assume.

  1. 0:37

    First Venomous Emergence

    Then 1:44, 3:26, 4:34. The long gap is the intermission interrupting the cycle, not a different cadence.

  2. 0:52

    First Stir the Depths

    Then 2:00, 3:42, 4:49. It arrives 11 seconds ahead of each Ravenous Feast, so the wave lanes and the soak land together rather than separately.

  3. 1:03

    First Ravenous Feast

    Then 2:11, 3:53, 5:01. This is the venom economy: four cleansing windows in a five minute kill, so a player who misses one carries those stacks for over a minute.

  4. 2:30

    Intermission: Sanguine Storm and Vile Flood

    2:30 in all five kills, with Vile Flood's second cast four seconds later.

  5. 5:30, then 8:00

    Later intermissions

    The playbook's schedule, not a measurement: the slowest sampled kill ended at 5:12, so nothing in the top 50 reaches the second one. Expect it only if your pull runs long.

Mechanics

What each mechanic asks of you

Eternal Venom

Everyone

The stacking nature DoT that everything applies. What the cap does to you depends on your difficulty, and only Feast soaks remove stacks.

Failure: 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.

Raid Finder
11 stacks: 50 percent of max health, then an 8 second stun.
Normal
11 stacks: 85 percent of max health, then an 8 second stun.
Heroic
10 stacks and you die. The tightest cap of the four.
Mythic
11 stacks and you die.

Ravenous Feast

Three soak groups

Split-soak all three rapid strikes with the assigned groups, brace the knockback, and treat the removed stack as the reward.

Failure: A missed strike is heavy raid damage AND the raid keeps its venom stacks - the fight's economy collapses.

Raid Finder
One player must be struck, or everyone takes the strike in full.
Normal
One player must be struck, or everyone takes the strike in full.
Heroic
One player must be struck, or everyone takes the strike in full.
Mythic
Four players must be struck, or everyone takes the strike in full.

Stone Breaker

Tanks

Each slam must hit a player: the assigned tank takes three, then swaps out for 1.5 minutes while amplified.

Failure: An empty slam is raid-wide damage and a knockback; a fourth slam on the same tank is usually fatal.

Caustic Deluge and Caustic Globules

Vexhul tank and assigned soakers

Tank into the pushback; one player soaks each Globule inside 10 seconds.

Failure: An unsoaked Globule applies Eternal Venom to every player in the raid at once.

Coiling Ichor

Debuffed players and healers

Run to the edge while pulsing damage to those nearby, get single-target healing, and drop the expiry puddle in a planned safe lane.

Failure: Ichor walked through the raid or dropped mid-platform poisons the shrinking play space.

Uncoiled Wrath

DPS

Keep both serpents' health even to the very end.

Failure: The surviving serpent gains stacking increased damage every 3 seconds - a staggered kill becomes a wipe timer.

Raid Finder
10 percent more damage every 3 seconds, stacking.
Normal
10 percent more damage every 3 seconds, stacking.
Heroic
25 percent more damage every 3 seconds, stacking.
Mythic
30 percent more damage every 3 seconds, stacking.

Raid response: Tanks stay in range through every reposition, including intermission relocations.

Toxic FumesPermanent

Both serpents fill the air with fumes. Passive raid-wide damage all fight.

Raid response: Healers pace throughput; there is no downtime to bank.

Caustic DelugeVexhul

Vexhul funnels toxin into her target for 5 seconds, splashing acid that leaves Caustic Globules.

Raid Finder
100529 every half second. Each acid splash hits for 167548.

Caustic GlobuleVexhul

Explodes after 10 seconds, applying Eternal Venom to all players - unless one player soaks it first.

Raid response: Assigned low-stack players soak each Globule deliberately.

Venomous EmergenceVexhul

Summons Spawn of Vexhul that spew a spinning toxic beam around the arena. The call itself venoms the raid.

Raid Finder
50264 Nature and a venom stack to everyone.
Normal
65921 Nature and a venom stack to everyone.
Heroic
92660 Nature and a venom stack to everyone.
Mythic
125011 Nature and a venom stack to everyone.

Stir the DepthsVexhul

A 6 second churn that damages everyone and forms waves pathing across the arena.

Raid Finder
50264 every 2 seconds. The waves tick 50264 a second.
Normal
65921 every 2 seconds. The waves tick 65921 a second.
Heroic
108139 every 2 seconds. The waves tick 123588 a second.
Mythic
166681 every 2 seconds. The waves tick 125011 a second.

Raid response: Sidestep the wave lanes as they cross.

Ravenous FeastIthraz

Three rapid split-soak strikes with knockback. Each soak eats one Venom stack and leaves you Feasted, which blocks the next one.

Raid Finder
603174 Physical a strike, split. One player is enough.
Normal
791057 Physical a strike, split. One player is enough.
Heroic
1668437 Physical a strike, split. Feasted adds 800 percent Feast damage for 8 seconds.
Mythic
4625407 Physical a strike, split. Four players must be struck.

Raid response: Three groups, one strike each, so nobody wastes a strike while Feasted.

Coiling IchorIthraz

Debuffed players pulse damage to those nearby and drop a puddle on expiry.

Raid response: Run out, take spot heals, place the puddle at the planned edge.

Stone BreakerIthraz

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.

Raid Finder
670193 a slam. An empty slam hits everyone for 134039.
Normal
878952 a slam. An empty slam hits everyone for 175790.
Heroic
1421261 a slam. An empty slam hits everyone for 494352.
Mythic
2500220 a slam. An empty slam hits everyone for 916747.

Raid response: The assigned tank soaks three in a row, then swaps; immunities can cheat individual slams.

Submerge and Vile FloodFirst intermission at 2:30

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.

Raid response: Read the orb spin for the beam direction, shift to the new clean area by Ithraz, and dodge the frontal channel.

Sanguine StormIntermission

Ithraz showers the platform with gore for 18 seconds; each impact hits everyone within 4 yards.

Raid Finder
201058 Shadow an impact.
Normal
263686 Shadow an impact.
Heroic
370764 Shadow an impact.
Mythic
500044 Shadow an impact.

Raid response: Dodge the impacts while you read the orbs for Vexhul's beam direction.

Role plan

Your job in the pull

Tanks

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.

Healers

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.

DPS

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.

Everyone

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.
