wotlk classic naxxramas heigan the unclean featured image

Heigan the Unclean is the second boss of the Plague Quarter in Naxxramas. A master of traps and disco, Heigan the Uncleans fight involves the raid rhythmically moving around the arena to dodge the booby-trapped floor. This mechanic is often referred to as the safety dance, Heigan the Uncleans dance, or simply the dance.

Observe, Heigan the Unclean. The mastermind behind the plague cauldrons that turned the wilderness of Azeroth into the Plaguelands. It is said that Heigan has rigged the very walls and floors of Naxxramas itself with a vast array of traps, which he can trigger at will.” –Commander Eligor Dawnbringer

This guide will offer a detailed, step-by-step tutorial on how to keep up with Heigan the Unclean’s lively dancing and his deadly game of “the floor is lava”.

Role Summaries

Phase 1

  • Make sure you are in the correct position at all times.
  • Prioritize dodging Eruption over anything else.
  • Cure Diseases as fast as possible, even as a DPS.

Phase 2

  • Dancing is your top priority, dealing damage to Heigan the Unclean is secondary.

Phase 1

  • Being out of the Eruption zones is much more important than being at Heigan the Uncleans back.

Phase 2

  • You can’t deal much damage during this Phase, so focus purely on the dance.

Phase 1

  • Stay on the platform but further than 30-yards away from Heigan the Unclean.

Phase 2

  • You can DPS Heigan the Unclean during this Phase, but never do it at the cost of failing the dance.

Phase 1

  • Stay on the platform but further than 30-yards away from Heigan the Unclean.
  • Keep your eye on the melee, if one of them looks like they will be hit by Eruption, try to react preemptively.
  • If everyone is doing the mechanics correctly, there is very little damage, DPS when you have downtime.

Phase 2

  • If everyone is doing the mechanics correctly there is no damage during Phase 2, but you should still always keep an eye out for players taking a hit or two from Eruption.

Phase 1

  • Try to always be on the edge of the safe zone, to make sure your melee DPS can fit behind Heigan the Unclean.
  • You are the first response, melee will follow the boss blindly. If you move incorrectly, they move incorrectly.
  • Keep the boss at a reasonable range from the platform, to avoid ranged DPS being hit by Spell Disruption.

Phase 2

  • Dance with your friends, enjoy the downtime.


Phase 1

This Phase shows the basic concept of the dance, keeping it slow at first and allowing everyone to deal damage to Heigan the Unclean. Players will also be consistently hit with Decrepit Fever, which needs to be dispelled. As long as the mechanics are handled there is almost no healing needed here.

Phase 1

All players within 30-yards of Heigan the Unclean have their cast times increased by 300%. There isn’t really anything to do about this, if you have to be near him you have to be near him. Focus on instant casts where possible if you have this debuff.

A random player is debuffed with a Disease that deals 4500 Nature damage every 3-seconds as well as reducing the maximum health of everyone nearby by 50%. This needs to be dispelled as soon as possible using spells such as Abolish Disease, Cleanse, Cleanse Spirit, and Cleansing Totem. As long as your dispeller is on their toes this won’t be a problem, but if it isn’t dealt with you could end up spiraling downwards fast.

Every few seconds three of the four quarters of the room will erupt, dealing 6650 to 7350 Nature damage on hit. This can easily hit multiple times if you don’t move out fast enough. This is what gives the mechanic of the fight its name, the dance. Keep your feet moving at all times, you want to be in the safe quarter as fast as possible to reduce damage. If your friends don’t dance, you’re going to have to leave them behind.

During Phase 2 this ability is cast a lot more often.

Phase 2

Phase 2 speeds up Eruption and adds Plague Cloud into the mix, forcing players off the safety of Heigan the Uncleans platform.

All players on Heigan the Uncleans’ main platform will take 7500 Nature damage per second. Avoid this by not being on Heigan the Uncleans’ platform in Phase 2. You have to dance, sorry.

Raid Composition & Preparation

The only requirement for this fight is the ability to dispel diseases. This is done with spells such as Abolish Disease, Cleanse, Cleanse Spirit, and Cleansing Totem.

You will want between 3-6 Healers for this fight, the better your players are at dancing, the less there is to heal.

There are no strict requirements for DPS classes or specs here, you simply want a combination of good raid buffs and debuffs, as well as the best players you can muster.

You will only need one tank for this fight, a main-tank for Heigan the Unclean in Phase 1. This will usually be the tank that deals the least damage, so any other tanks can focus purely on DPS.

The Pull

On pull the main tank should immediately reposition Heigan the Unclean off of his platform and onto the cracked floor. Ranged players should take over his position atop the platform, while melee players and tanks will have to perform a slower dance to avoid Eruption.

The Fight

Phase 1

heigan phase 1

During Phase 1 Heigan the Uncleans platform is a safe space, meaning ranged classes can freely stand there and not have to worry about Eruption. They will still need to make sure they stay 30-yards away from Heigan the Unclean at all times to avoid Spell Disruption, but can otherwise simply stand on the platform without worry.

Heigan the Uncleans melee attacks deal very little damage, so most of the healers time will be reserved for players with Decrepit Fever, either dispelling it with abilities like Abolish Disease and Cleanse Spirit, or healing the targets. Occasionally a melee player may take a hit from Eruption; in those cases healers will need to heal them up quickly.

In this Phase the ground will erupt in the pattern of 1-2-3-4-3-2-1-2. To deal with this, start the encounter in the green zone marked 1, after the first Eruption, move to the blue zone marked 2, and so on, moving quadrant after every Eruption. The tank will want to be on the very edge of their quadrant, to make sure that melee DPS have enough room to safely be behind Heigan the Unclean.

Here are some of the main things that can go wrong in this phase:

  • Someone gets confused and fails the dance, being hit by Eruption repeatedly.
  • Fever isn’t dispelled in time, reducing everyone’s hit points by 50% and dealing heavy damage.
  • The boss isn’t positioned properly, causing melee to take Eruption hits if they stay behind the boss.
  • Healers get stacks of Spell Disruption, falling behind on healing and being unable to keep up.

After 90 seconds, Heigan the Unclean will teleport to his platform and begin Phase 2.

Phase 2

Phase 2 begins after 90 seconds, with Heigan the Unclean teleporting to his platform. Everyone will need to quickly move together to the green zone marked 1. This is the true dance, mimicking the dance of Phase 1 with the speed ramped up. Anyone still on Heigan the Uncleans platform during Phase 2 will be hit with Plague Cloud, taking massive Nature damage every second.

This dance will go in the same pattern as Phase 1, going through quadrants in the following order: 1-2-3-4-3-2-1-2-3-4-3-2. Melee players will only be able to do the dance during Phase 2, as Heigan the Unclean is too far away to hit.

Ranged DPS can continue dealing damage to Heigan the Unclean, but need to be very sure they still focus on dancing. This fight does not have an enrage, you have all the time in the world as long as you don’t have two left feet!

Here are some of the main things that can go wrong in this phase:

  • Players try to stay on Heigan the Uncleans platform, or melee DPS try to sneak in a few hits, dying to Plague Cloud.
  • Someone gets confused and fails the dance, being hit by Eruption repeatedly.

Phase 2 will last for 45-seconds, after which Heigan the Unclean will run towards whoever has the most threat and begin Phase 1 again, resetting the Eruption pattern to the green zone marked 1.

If everyone has their dancing shoes on, this fight is a piece of cake, dealing very little damage and having no enrage timer.

Congratulations on becoming the new lord of the dance, with Heigan the Unclean dead as disco, nothing stands between you and Loatheb, the final boss of the Plague Quarter.
