Raid boss guidesThe Venomous Abyss
Midnight Season 2 encounter guide

Entombed Sentinels

The raid splits in half, each side fighting one Guard - Acid or Blood - with its own mechanics, then swaps sides at every intermission to drop the stacking Mark. Boss health must stay even, because Vitriolic Stasis heals the lower Guard up to match the higher one.

Before the pull

Set the encounter assignments before pull

  • Special notes: no immunities, Blighted Blood is the dispel, and there are no interrupts.
  • Split the raid evenly before the pull: one half on the Acid Guard, one half on the Blood Guard, and plan the side swap at each intermission (they land near 0:45, 2:30, 4:15, and 6:00).
  • Tanks agree on positions at least 40 yards apart - within 40 yards of each other the Guards take 99 percent reduced damage from Ula'tek's Dominance.
  • Pick the puddle corners: Blood Venom void zones and dispel puddles all go next to existing puddles at the edge, never in fresh space.
  • Rehearse Helical Toxins: during the Stasis channel everyone is infected with 1 to 3 toxin stacks and must collide with a partner whose number brings the total to exactly 4.
Fight flow

Resolve the encounter in this order

  1. 01

    Split and separate

    Each half of the raid takes its Guard, tanks hold them 40-plus yards apart, and both sides keep damage even so neither Guard runs ahead on health.

  2. 02

    Blood side routine

    Group-soak each red Unstable Miasma circle, accept the Blood Venom stacks, and when they expire drop the void zone on the edge next to existing puddles. Healers dispel Blighted Blood near those same puddles.

  3. 03

    Acid side routine

    Dodge the green Living Venom lines aiming at the boss, step on Toxic Droplets before they explode, and hard-swap to the Venom Coagulation add to stop its pulsing damage.

  4. 04

    Watch the tank hits

    Empowering Slam and Bloodvenom Injection are the big tank moments - use cooldowns, and remember the Guard keeps hitting harder until the tank targets swap.

  5. 05

    Intermission collision

    At 100 energy the Guards clash in the middle and the lower one heals up to match the higher. During the channel, pair up so your Helical Toxin numbers total exactly 4 - 1 finds 3, 2 finds 2 - to clear the toxin.

  6. 06

    Swap sides and repeat

    After every intermission the halves trade Guards so the stacking Mark of Acid or Blood falls off. Re-establish the 40 yard separation immediately and repeat until both die together.

Mechanics

What each mechanic asks of you

Ula'tek's Dominance

Tanks

Keep the Guards more than 40 yards apart at all times - inside that range they take 99 percent reduced damage.

Failure: Bosses drifting together turns the raid's damage off and wastes the timer.

Mark of Acid and Mark of Blood

Everyone

Fighting within 40 yards of a Guard stacks a damage-over-time Mark that only falls when you swap to the other Guard - which is why sides trade at each intermission.

Failure: Staying on one side all fight ramps the Mark until healers cannot keep up.

Vitriolic Stasis and Helical Toxins

Everyone

During the clash channel, collide with another player so your combined toxin applications equal exactly 4.

Failure: Wrong totals or unpartnered players deal raid-wide damage on top of the intermission.

Unstable Miasma and Blood Venom

Blood side

Group-soak the marked red circle, then walk the expiring Blood Venom stacks to the edge - the void zone size scales with stacks.

Failure: A solo soak or a center drop floods the arena with avoidable void zones.

Living Venom, Toxic Droplets, and Venom Coagulation

Acid side

Dodge the slime lines being sucked back to the boss, step on droplets to pre-empt their explosion, and nuke the Coagulation add on sight.

Failure: Ignored droplets and a live Coagulation add turn the acid side into constant unplanned raid damage.

Blighted Blood

Healers

Dispel the ticking Shadow debuff with the player positioned near existing puddles, since the dispel drops one.

Failure: Dispelling in the open scatters puddles through the play space.

Ula'tek's Dominance

Permanent

The Guards take 99 percent reduced damage while within 40 yards of each other.

Raid response: Tanks own the geometry; everyone else respects the two-camp split.

Mark of Acid / Mark of BloodPermanent

Players near a Guard take stacking damage over time until they swap Guards.

Raid response: Swap sides at each intermission to reset the stack.

Vitriolic StasisAt 100 energy

The Guards clash in the middle and the lowest-health Guard heals up to match the highest.

Raid response: Keep health even all fight so the heal is worthless, and use the channel to resolve toxins.

Helical ToxinsIntermission

Everyone gains 1 to 3 toxin applications and must collide with a partner to total exactly 4.

Raid response: Call pairings fast: 1s find 3s, 2s find 2s. Leftovers pair across the room before the channel ends.

Empowering SlamAcid Guard

A large tank hit that increases the Guard's damage dealt until the tank targets swap.

Raid response: Cooldown the hit and take the swap on schedule.

Living Venom

Acid Guard

Ejected slime is sucked back to the boss, damaging players in its path.

Raid response: Never stand between the slime and the boss; sidestep the green lines.

Venom CoagulationAcid Guard

Slime forms an add that pulses raid damage until killed.

Raid response: It is the acid side's kill priority the moment it forms.

Toxic DropletsAcid Guard

Droplets form and explode if nobody steps on them.

Raid response: Squish them early - one player per droplet.

Blighted BloodBlood Guard

A dispellable ticking Shadow debuff.

Raid response: Dispel next to existing puddles only.

Bloodvenom InjectionBlood Guard

A large tank hit that applies a stacking damage-over-time blood venom.

Raid response: Tank cooldowns, then swap before the stack compounds.

Role plan

Your job in the pull

Tanks

Hold the 40 yard separation, drop your puddles near existing ones on the edge, and treat Empowering Slam and Bloodvenom Injection as scheduled cooldown moments with a swap after.

Healers

Dispel Blighted Blood next to existing puddles, cover the Miasma group soaks, and split coverage so both camps always have healing - the intermission clash is the big raid-wide window.

DPS

Keep the two Guards' health even to make Vitriolic Stasis heal for nothing, and priority-target the Venom Coagulation add whenever it forms.

Everyone

Know your toxin number before the clash and find your partner immediately. On Mythic, orange-circle players must connect only with other orange-circle players - touching anyone else deals heavy damage and a knockback.
