Mug'Zee, Heads of Security - Mythic Boss Tactics

Raid Composition: 2 Tanks / 4 Healers / 14 DPS
Encounter Type: Pure single-target fight
Enrage: Hard enrage at 100 Energy (P1 or P2)
Heroism/Bloodlust: Use at 40% boss HP
Recommended Utility: Immunities highly valuable

Mechanics Overview
Head Honcho – Room side swap only triggers if all players are on the same side. Failing this leads to enrage at 100 energy.
Earthshaker Gaol – Each cast spawns one extra Gaol. Starts with 2, ends with 4 active simultaneously. Enraged Gaols cannot be damaged, resulting in a wipe.
Frostshatter Boots – Damage-over-time until fire is touched. Arrows handled like Heroic – behind wall or mine. Fire touch required to remove debuff.
MK2 Electro Shocker – Add is shielded unless hit by Finger Gun. Immune to damage otherwise.
Electrocution Matrix – Appears at 40%, splitting room with a deadly electric beam. Easily handled with correct movement.
Unstable Crawler Mines – Lethal to non-tanks. Tanks must soak with cooldowns or immunities. Monks can survive with Dance of the Wind.
Strategy Summary
General Notes: Use 4 healers to skip a side swap at 4:00. This removes one debuff stack and smooths healing in the last phase.
Mine Soaking
Phase 1:
Set 1: Paladin + Offtank + Paladin using Bubble x2
Set 2: Paladin + Offtank + Paladin using Bubble x3
Phase 2:
Paladin soaks all 4 with Bubble
Two other mines frozen via arrows
Monks can soak if Paladin unavailable. Use Dance of the Wind for high DR.
Prison Assignments
Prison numbers increase per cast. Prioritize self-escaping classes:
Monks, Warlocks, DHs, Mages, Void Elves
Examples:
Set 1: Monk + Lock / DH + Mage
Set 2: Monk + Lock + Healer / DH + Healer + Mage / Randoms + Healer
Set 3: Healer + Tank + Monk / Healer + Lock + Mage / Healer + Void Elf + DH / 3 defensively-strong non-immunity players
Assign immune soakers to the first two prisons for in-prison soaking. Avoid assigning immunes unless they can escape themselves.
Rocket Soaks
Occurs only 3 times:
1st: 2 tanks + 5 immunes
2nd: Entire raid except 5 immunes & tanks
3rd: Same as 1st
Frontal Damage
Spray and Pray / Finger Gun: High tick damage. Require externals and sustained healing.
Double Whammy: Big spike. Target must be topped and pre-assisted with defensives.
Phase 1 Walkthrough
Start on opposite side of entrance (metal). Pull near wall.
Stack initially to bait mine spawns, then loosely spread.
Soak 1st rocket: Only tanks and immunes.
Frontals: Handle Double Whammy → Spray and Pray.
Trigger side swap: Mage blinks into dirt side. Everyone must move.
Stone Side:
1st Prisons: Place on markers. Assigned players enter.
Stack by boss to bait arrows.
After Boots: Enter/exit fire to cleanse, move per callout.
Metal Side:
Move boss near Shocker add.
Finger Gun: Ensure both adds get hit to break immunity.
Trigger side swap moving boss.
Back to Metal:
Handle 2nd mine wave same as 1st.
2nd rocket: Middle of room, soak with full raid (excluding tanks & immunes).
Return to Dirt:
Double Whammy + Spray and Pray
Trigger side swap post-abilities.
Next Prisons:
3 prisons appear. Tank boss between them.
Post gold ability: Move boss near middle fire for Boots cast.
Boots/Arrows Handling:
Stack to bait arrows.
Fire touch removes Boots.
Arrow players hide behind walls.
If Finger Gun targets you, hit nearest Shocker only.
Key Phase 1 Goal: Push boss to 40% before 100 energy. Use Hero at 70 if needed. Failing push adds permanent damage stack post-intermission.
Once you've moved the boss to the dirt side again, you’ll deal with another prison sequence—this time with three groups. Position the boss between the prisons, and once the tank uses their gold ability, reposition them slightly closer to the central fire pool. This is to prepare for the upcoming Frostshatter Boots cast.
Make sure players are stacked tightly near the boss to attract arrow spawns to manageable locations. The player managing room control must remain on the opposite side to maintain clear walls. As the Boots cast finishes, those affected should step into fire briefly to cleanse, then move out immediately. If targeted by arrows, hide behind the nearest walls.
If someone gets Finger Gun, they can disable the close Shocker add, but don’t aim for both adds—this increases the risk of clipping allies with unnecessary frontal damage.
Your objective here is to drive the boss below 40% health before it reaches 100 energy. If your damage output is slightly behind, trigger your Heroism/Bloodlust around 70 energy to help push through. Failing that, a side swap can be forced to allow some Intermission practice—but doing so adds a permanent debuff to the boss, increasing all damage it inflicts for the rest of the fight.
Intermission Strategy
This section is mechanically straightforward, provided players avoid swirl zones and steer clear of the frontal cone attacks from Mug'Zee’s twin cannons.
Due to the electric barrier splitting the space, Mug'Zee is forced into a specific movement script. Initially, the boss will always charge in the same direction. After this, a tank should taunt to reposition Mug'Zee closer to the starting point.
Expect another charge to the diagonally opposite corner. Here’s where bugs may occur: instead of following its programmed pattern, Mug'Zee might continue in an unintended direction. To prevent this, assign a Monk to taunt just before the second spin ends, followed immediately by a tank taunt. This taunt sequence usually resets the boss pathing correctly and ensures the charge ends on the metal side as intended. Don’t worry—players won’t be trapped by the energy barrier during this.
Phase 2 Strategy
The second phase kicks off with mine spawns. Stack close to the boss to bait their location. The tank needs to quickly and decisively handle mine pops to avoid overlapping with Frostshatter Boots mechanics. Healers should preemptively prepare cooldowns, and all players should use personal defenses and health stones if necessary. This part is particularly demanding.
Once the four mines are handled, everyone should reposition toward the fire pool. Boots wearers cleanse in fire, arrow targets hide behind remaining mines, and the rest should head to their assigned prison groups.
Next, a Rocket cast targets the area between Purple and Green markers. Immunity-capable players and tanks should soak this—anyone else in a prison must avoid soaking unless their class allows escape or self-cleansing.
When prisons break, stack back up. A Finger Gun will target a random player—use it to hit all the shocker adds, but only prioritize killing the one within melee range. The others can be ignored.
Then, two additional frozen mines will need to be soaked. If available, use Netherwalk from Demon Hunters or similar immunities. Missing these soaks this deep into the fight can lead to a wipe, so everyone needs to be attentive.
Final Phase and Kill
As the boss begins casting Double Whammy and Spray and Pray, reposition behind Mug’Zee near the wall to safely dodge these abilities. Players should remain tightly grouped with their backs facing toward the center of the metal platform. This creates optimal mine spawn placement.
Gradually kite the boss toward the dirty side. As mines spawn, use AoE slows to keep them grouped up. Position yourself close to the fire again, and when Mug’Zee casts Boots, step into the flames at the last second before stepping out.
To close the encounter, move behind the mines to avoid the final arrow volley. Be careful not to accidentally walk into any lingering mines.
Stay focused—and defeat Mug’Zee.
