Introduction
This fight is all about movement, it even has its own title, the “Heigan Dance”. Knowing the safe zones is the key to defeating this encounter. Make sure everyone in the raid understands where they are and how the encounter works or else you will deal with many wipes. This fight is exactly the same in both normal (10 man) and heroic (25 man) versions so we will just post this one strat.
Abilities
Heigan the Unclean has approximately 9,270,000 hit points on Heroic and 3,060,000 hit points on Normal.
Phase One
Spell Disruption - This is a 20-yard aura around Heigan the Unclean. It will increase cast times by 300%.
Decrepit Fever - This is a disease applied to a random player which will do 4,500 Nature damage every 3 seconds and reduce the maximum hit points of every player within 20 yards by 50%.
Phase Two
After 90 seconds Heigan will teleport to the middle of the raised platform and begin channelling.
Plague Cloud - Deals 7,500 Nature damage a second to any player remaining on the raised platform during Phase Two.
Eruption - Three quarters of the remaining area of the room will be hit by eruption every few seconds during Phase Two. Does 6650 to 7350 Nature damage on a hit. Near the edge of a safe spot players will only be hit once. In the middle of unsafe spots they will be hit multiple times which is generally fatal.

Strategy
Phase One
The raid needs to move into the room all at once because there is a gate on the door that will lock people out. The main tank should pick up heigan and tank him in safe zone 1. Melee DPS will also stay with the tank out on the floor during this phase. Range DPS and Healers will stay up on the platform. Shortly after you engage Heigan and get positioned, ooze will start erupting out of the ground. Zone 1 will be the first safe spot, when the ooze comes up in 2, 3 and 4 you should then move Heigan, melee dps, and the main tank to Zone 2. When the ooze comes up again it will hit spots 1, 3 and 4. You will then move on to safe zone 3 and so on. The safe zones will always go in the same order, back and forth across the room, 1, 2, 3, 4, 3, 2, 1.
Cleansing the disease is also very important during this phase, if a melee gets the disease there is a high chance the ooze can 1 shot them if they don’t get cleansed. To make sure this is taken care of, put shaman in the melee groups and have them dropping disease cleansing totem in Zone 2, 3 or the platform. Melee also need to understand where the safe zones are. Heigan will sometimes lag behind the tank so you can’t always depend on them to have the boss in the right position.
This phase will last 90 seconds and then Heigan will teleport to the platform and begin phase 2.
Phase Two
Heigan will teleport to the platform and the entire raid needs to move off into Zone 1. This is known as the heigan dance. The ooze will shoot out of the floor just like it did during phase 1, except much faster. As soon as it pops up in Zone 2 you need to start moving to zone 2, then it will shoot up again, then move to zone 3, then to 4, then to 3, etc. The raid will mostly be running the entire time without stopping. Some common mistakes during this phase are people running too far into zone 1 and 4, which does not give them enough time to get to the next safe zone. It is important that you do not try and follow someone else during this phase, due to latency you will most likely not make it to the next zone in time.
During this phase Heigan also has an aura that hits for 7,500 damage a second. So you need to be on the floor and at least 20 yards away from him. This phase will last for about 4 passes through the room. Once it ends, Heigan will run back to the main tank and everyone needs to get back into their same positions as Phase 1. Every time a new phase begins, Zone 1 will always be the first safe spot. Heigan also does not drop agro so he will always run right back to the tank when phase 2 ends.
The fight will continue these 2 phases until Heigan is dead. Do not stress out on your raid if you wipe a few times on your first night, the dancing takes a little bit of getting used to. Once everyone learns how it works you will 1 shot it each week with no problems.
