Altar of Fangs M+ Guide

Altar of Fangs is a compact three-boss dungeon inside the Vaults of Atal'Utek on the Coiled Isle. Serpent cultists, carrion feeders, and ritual venom define the run — execution spikes on Zul'jan's beam soaks and venom stacks, but Rav'i and The Writhing Coil punish sloppy shield breaks and missed interrupts first.

30:00Midnight12.1

Route and gates

Destroy all 6 Caustic Mist Totems before Rav'i — the path does not open until they are cleared.
Grab the Unfinished Mixture buff after The Writhing Coil (25 Cooking or Alchemy) — Mutating Elixir lasts the rest of the run.
The route is linear with no skips; enemy forces come from trash density, not hidden packs.
Save major cooldowns for Zul'jan; the first two bosses die quickly when mechanics are handled cleanly.
A 30-minute timer is mid-length; wasted time on trash before Rav'i is the most common timer leak.

Trash that ends keys

Interrupt Piercing Hiss on Primal Serpents and Mass Envenom on Ascendant Serpents — both are required.
Face Twinfang Harrowers away from the group for Toxic Breath; dispel Paralyzing Shots immediately.
Interrupt Evolve on High Evolutionists before Envenom becomes Mass Envenom.
Kill Living Venom one at a time — Venom Burst on death chains party damage.
CC Hatchlings from egg pulls; they fixate random players with Nascent Hunger.

What to kick

Always kick

Miss one and someone dies.

Piercing Hiss
Primal Serpent
Heavy damage channel — interrupt every cast on every pull.
Mass Envenom
Ascendant Serpent
Raid-wide poison — assign a dedicated interrupter.
Evolve
High Evolutionist
CC or interrupt before Envenom upgrades to Mass Envenom.

Kick when you can

Costs healing or time if it goes off.

Mass Envenom
Ula'tek's Chosen
Also used by Ascendant Serpent — rotation must cover both.

Spare kicks

Only when nothing above is casting.

Paralyzing Shots
Twinfang Harrower
Dispel or freedom; not interruptible but must be handled fast.

Rav'i

A multi-headed hydra that shields in carrion piles during Ssscavenging. Move her to the correct bone pile, soak Messy Eater puddles to break the shield, and spread for Triple Shot and Regurgitate waves.

The fight, in order

Pull & position
Tank faces Rav'i away from the group. Track which bone pile lacks a Twinfang corpse.
Pull Rav'i to center and face her away from the group so Regurgitate and Triple Shot do not cleave melee. Call out which bone pile never received a Twinfang corpse — that pile is your safe Ssscavenging spot for the whole fight.
Tank
Ssscavenging
Drag boss to the correct bone pile. Soak Messy Eater puddles to break the shield.
The moment Ssscavenging starts, tank drags Rav'i onto the pile without a Twinfang corpse. Everyone steps into every Messy Eater soak circle to damage the shield — standing outside lets the shield linger and healing falls behind. Wrong pile triggers Feeding Frenzy and is usually a wipe.
Everyone
Spread & dodge
Loosely spread for Triple Shot. Dodge Regurgitate waves toward the marked player.
Give each player space so Triple Shot does not hit multiple people. When Regurgitate targets someone, everyone else moves out of the wave path — dispel disease on anyone clipped. Do not stack in the boss hitbox during these casts.
Everyone
Ravenous Stomp
Pre-top the group before the stomp hits. Resume boss damage once shield is broken.
Healers pre-shield and top the group before each Ravenous Stomp — it is a predictable raid-wide spike that kills untopped groups. DPS should not greed damage during the cast window; resume boss damage once the shield phase ends.
Healer
Repeat & win
Loop pile positioning, shield breaks, and spread discipline until Rav'i dies.
Every cycle repeats: call the safe pile, soak through Ssscavenging, spread for shots and waves, top before stomp. Tank uses active mitigation on Hydrastrike between phases. Missing one pile call or one soak rotation snowballs into a long shield phase.
Everyone

Do this

Before Ssscavenging: tank drags Rav'i to the bone pile that did NOT get a Twinfang corpse — wrong pile triggers Feeding Frenzy.
During Ssscavenging: everyone steps into Messy Eater soak circles and pools damage to break the shield fast.
Loosely spread for Triple Shot — do not cleave allies with the random-target shots.
Dodge Regurgitate waves shooting toward a random player; dispel disease if someone gets hit.
Top the group before Ravenous Stomp — it is a predictable raid-wide spike.
Tank faces Rav'i away from the group; Hydrastrike makes her melee output brutal on the active tank.

Not this

Letting Rav'i Ssscavenge on a pile with a Twinfang corpse — Feeding Frenzy is a near-wipe.
Ignoring Messy Eater soaks during the shield phase — shield lasts too long and healing falls behind.
Stacking during Triple Shot or Regurgitate overlap.
Standing in Septic Spatter circles from trash or boss puddles.

Safe pile

One bone pile never got a Twinfang corpse.
Tank drags Rav'i onto that pile before the cast.
A corpse pile triggers Feeding Frenzy.

Ssscavenging

Watch which bone pile did NOT receive a Twinfang corpse during the fight. Tank moves Rav'i onto that pile before Ssscavenging starts. Never let her scavenge a pile with a corpse on it.

Rav'i retreats into a carrion pile and gains a damage shield. Wrong pile choice enrages her.

Call it: Call the safe pile out loud before the cast — Feeding Frenzy is the primary wipe.

TankEveryone

Soak the shield

Rav'i shields up inside the pile.
Every player steps into a soak circle.
The soaks damage the shield until it breaks.

Messy Eater Soaks

Every player steps into Messy Eater soak circles during the shield phase. Pool damage on the shield — do not stand outside and heal through a long shield.

During Ssscavenging, soak circles spawn that must be stood in to damage the shield.

Everyone

Defensives, burn

Rav'i scavenges a pile with a Twinfang corpse.
She enrages: massive damage and poison.
Everyone uses a defensive and burns.

Feeding Frenzy

Prevention only — drag her to the correct bone pile before Ssscavenging. If Frenzy happens, pop every defensive and burn; you cannot kick the enrage.

If Rav'i scavenes a pile with a Twinfang corpse, she enrages with massive damage and poison.

Everyone

Loose spread

Rav'i fires at random players.
Spread loosely so no shot hits two people.
Use a personal if it overlaps Ravenous Stomp.

Triple Shot

Loosely spread — give each player space so Triple Shot does not hit multiple people. Use a personal if it overlaps with Ravenous Stomp.

Rav'i fires at random players. Standing near allies cleaves the damage.

Everyone

Leave the path

A wave shoots from Rav'i toward one random player.
Everyone else steps out of its path.
Dispel the disease on anyone it clips.

Regurgitate

Identify the targeted player and move out of the wave path. Dispel disease on anyone clipped — the DoT stacks fast on Fortified weeks.

Waves shoot toward a random player, leaving disease on anyone hit.

Everyone

Top up first

Healer tops and shields the group before the cast.
The stomp then hits everyone at once.
Do not greed damage during the cast.

Ravenous Stomp

Healers pre-shield and top the group before each stomp. DPS should not greed damage during the cast window.

Raid-wide physical stomp that hurts if the group is not topped.

HealerEveryone

Mitigate, face away

Tank faces Rav'i away from the group.
Use active mitigation for the heavy melee hits.
Mitigate again after each Ssscavenging phase.

Hydrastrike

Tank uses active mitigation on pull and after each Ssscavenging phase. Face the boss away so Triple Shot and Regurgitate do not clip the group.

Rav'i hits the tank with high melee damage between mechanics.

Tank

Your job

Tank

Track which bone pile lacks a Twinfang corpse and call it before Ssscavenging.
Drag Rav'i onto the safe pile the moment Ssscavenging starts — wrong pile is a wipe.
Face the boss away from the group for Regurgitate and Triple Shot cleave avoidance.
Active mitigation for Hydrastrike; swap if melee damage climbs after a long shield phase.

Healer

Pre-top before Ravenous Stomp every time — it is the main predictable spike.
During Messy Eater soaks, expect sustained shield-phase damage; ramp before Ssscavenging.
Dispel Regurgitate disease immediately; stacks punish on Fortified.
If Feeding Frenzy triggers, call for externals — healing alone will not hold.

Damage

Step into every Messy Eater soak during Ssscavenging — shield break is everyone's job.
Loosely spread for Triple Shot; never stack in the boss hitbox.
Dodge Regurgitate waves; do not stand in the targeted player's path.
Hold burst for windows after the shield breaks, not during soak phase.

From the Encounter JournalBlizzard's own notes and ability list for Rav'i

Rav'i's domain is littered with Carrion Piles from the many sacrificed creatures thrown into the pit. Occasionally, Rav'i makes a Ravenous Stomp, dropping Fresh Meat. Upon running out of energy, Rav'i begins Ssscavenging from the nearest Carrion Pile. If the Carrion Pile contains Fresh Meat, Rav'i goes into a Feeding Frenzy.

Tanks

Ravenous Stomp drops Fresh Meat on some Carrion Piles.
Carrion Piles with Fresh Meat cause Rav'i to go into a Feeding Frenzy.
Rav'i inflicts melee damage with Hydrastrike.

Damage

Rav'i stops Ssscavenging or her Feeding Frenzy when her absorb shield is removed.
Ssscavenging and Feeding Frenzy both continuously apply Carrion Burst to all players until stopped.
Regurgitate hurls waves of acid in a player's direction.

Healers

Triple Shot inflicts damage around 3 players over time.
While Rav'i is eating, she afflicts all players with increasing applications of Carrion Burst and is a Messy Eater.
Regurgitate hurls waves of acid in a player's direction.
