Maisara Caverns is one of the four new dungeons added in WoW Midnight Season 1's Mythic+ rotation, and at +10 it is widely considered the hardest key in the patch 12.0.5 pool. The instance has three bosses (Muro'jin & Nekraxx, Vordaza, and Rak'tul, Vessel of Souls) plus two mini-bosses (Rokh'zal and Zil'jan) and dense trash packs that punish loose pulls. This guide covers each boss in order, the trash that decides whether you keep the timer, and where most +10 pugs lose runs.
If you have been pugging keys at +7 through +10 this season, this is the dungeon where group composition and kick rotations matter most.
Each boss writeup that follows covers the kit, the kill pattern, and the specific call-out that decides whether the pull goes clean or the run is over.
Maisara Caverns is laid out as a horseshoe: front pools with Vilebranch trolls and Dread Souleaters, a left fork to Muro'jin & Nekraxx, the undead wing leading to Vordaza (via Rokh'zal), and a final bridge crossing to Zil'jan and Rak'tul. Trash density rewards two-pack chains over mega-pulls unless your tank has the cooldowns to eat two-and-a-half on the bridge approach.
Which wing you clear first decides whether the team hits the affix forces requirement on time. Most +10 routes go undead wing first to get Rokh'zal out of the way while cooldowns are still up.
Muro'jin (the troll hunter) and Nekraxx (his beast companion) share a health pool model that punishes uneven damage. If one drops to roughly 30 percent while the other is still high, the surviving target gains Bestial Wrath (Muro'jin) or Revive Pet (Nekraxx) and the fight effectively restarts. Cleave them within 5 to 10 percent of each other and burn the final phase together.
Where pugs lose this fight: a DPS pushes Nekraxx ahead, Bestial Wrath triggers, and the next Flanking Spear lands while the tank is repositioning into open space. Mark Nekraxx with skull and Muro'jin with X; assign a single DPS to kite swap if the pet jumps.
Vordaza is a Vilebranch necromancer who summons Unstable Phantoms with Wrest Phantoms. The wipe condition is not raw damage; it is the stacking Lingering Dread debuff applied by Final Pursuit when phantoms are detonated incorrectly.
The fight runs cleanest when one ranged DPS is dedicated to phantom soaks and rotates with a melee partner. Healers should track Lingering Dread stacks and call for a defensive at 3 stacks. The mini-boss Rokh'zal is encountered in this wing before Vordaza. He casts Ritual Sacrifice that pulls a non-tank player onto an altar; the rest of the group breaks the channel before the cast finishes.
Where pugs lose this fight: a melee soaks alone because the assigned ranged got clipped by Unmake, Lingering Dread hits 3 stacks, and the targeted player evaporates inside two ticks. Assign two soakers, not one, even if it costs a global cooldown.
Rak'tul is a dire troll bound by the distilled souls Vordaza was harvesting. The fight has two phases and an intermission that drags the group into the spirit realm. How the group handles the intermission decides whether the fight is tight or clean.
The first phase is a positional execution fight. The second phase rewards groups who built Spectral Residue stacks in the intermission.
Where pugs lose this fight: groups burn Malignant Souls in the intermission for safety, then come out of the spirit realm with zero Spectral Residue and run out of damage cooldowns before the boss enrages. CC is non-negotiable; kicks and slows beat damage every time. A group that pushes a timed Maisara key with consistent intermission CC will see noticeably cleaner phase-2 windows.
Most pug timer losses on Maisara Caverns happen on trash, not bosses. The standout packs:
The two mini-bosses are gated checkpoints, not optional:

Maisara Caverns is a Midnight Season 1 Mythic+ dungeon located in the Zul'Aman region. The entrance is in the southern Vilebranch troll area; the in-game waypoint command is /way 43.0, 39.5 on the appropriate continent map.
Three main bosses (Muro'jin & Nekraxx, Vordaza, Rak'tul Vessel of Souls) and two mini-bosses (Rokh'zal in the Vordaza wing, Zil'jan on the bridge before the final boss).
Cleave both bosses within 5–10% of each other and burn the final phase together. If one drops to roughly 30% while the other is still high, the surviving target gains Bestial Wrath or Revive Pet and the fight effectively restarts. Mark Nekraxx with skull and Muro'jin with X.
Soak Unstable Phantoms in pairs, not one at a time and not in groups of three. Soaking solo or bunched applies Lingering Dread stacks via Final Pursuit; the stacks kill the targeted player. Assign one ranged and one melee DPS to a phantom-soak rotation.
Soulrending Roar pulls the group into the spirit realm. Malignant Souls spawn; CC them rather than killing them. Each CC'd soul grants Spectral Residue stacks that amplify damage and healing in phase two. Groups that burn the souls for safety lose phase-two damage and timer.
At +10 keys and above, Maisara Caverns is widely regarded as the hardest of the eight Midnight Season 1 dungeons. Mechanic overlap in the back half, the Vordaza phantom rotation, and the Rak'tul intermission CC requirement all reward coordinated play more than the other seven dungeons.
Notable named drops include Vessel of Tortured Souls, Liferipper's Cutlass, and Traitor's Talon. Loot ilvl scales with the keystone level: +7 keys drop Hero-track 259, +10 drops Hero 266, and the weekly Great Vault rolls up to Myth-track at the top end. Reaching Keystone Hero on Maisara Caverns also unlocks the teleport portal.
