Mythic+ guide · Midnight · Patch 12.1
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.
Heavy damage channel — interrupt every cast on every pull.
Raid-wide poison — assign a dedicated interrupter.
CC or interrupt before Envenom upgrades to Mass Envenom.
Also used by Ascendant Serpent — rotation must cover both.
Dispel or freedom; not interruptible but must be handled fast.
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.
Pull to win — follow each phase in order every time the loop repeats.
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.
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.
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.
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.
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.
Rav'i retreats into a carrion pile and gains a damage shield. Wrong pile choice enrages her.
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.
Officer tip: Call the safe pile out loud before the cast — Feeding Frenzy is the primary wipe.
During Ssscavenging, soak circles spawn that must be stood in to damage the shield.
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.
If Rav'i scavenes a pile with a Twinfang corpse, she enrages with massive damage and poison.
Prevention only — drag her to the correct bone pile before Ssscavenging. If Frenzy happens, pop every defensive and burn; you cannot kick the enrage.
Rav'i fires at random players. Standing near allies cleaves the damage.
Loosely spread — give each player space so Triple Shot does not hit multiple people. Use a personal if it overlaps with Ravenous Stomp.
Waves shoot toward a random player, leaving disease on anyone hit.
Identify the targeted player and move out of the wave path. Dispel disease on anyone clipped — the DoT stacks fast on Fortified weeks.
Raid-wide physical stomp that hurts if the group is not topped.
Healers pre-shield and top the group before each stomp. DPS should not greed damage during the cast window.
Rav'i hits the tank with high melee damage between mechanics.
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.
