Positioning & Kiting

Heigan's room is divided into four zones that erupt in a repeating pattern: zone 1, zone 2, zone 3, zone 4, then back — zone 3, zone 2, zone 1, and repeat. During Phase 1, ranged players and healers stand on the raised platform at the back of the room (safe from Eruptions). The main tank holds Heigan on the floor near the platform edge. During Phase 2, Heigan teleports to the platform and poisons it — everyone must jump down to the floor and run the dance pattern through the safe zones. The diagram above shows the movement path through the four zones.
Loathebboss▾

HP: 5,329,600
Boss Abilities
Corrupted MindAfter any player casts a healing spell, ALL of their healing spells are locked out for 60 seconds. Each healer can only cast one heal per minute. This is the core mechanic of the fight.
Inevitable DoomUnavoidable 2,550 Shadow damage to all players after a 10-second debuff. Starts at 2 minutes into the fight (every 30 seconds). After 5 minutes, frequency increases to every 15 seconds.
Fungal Bloom (Spore)Spores spawn near Loatheb every ~12 seconds. When killed, grants up to 5 nearby players +50% melee critical strike chance, +60% spell critical strike chance, and zero threat generation for 90 seconds.
Remove CurseLoatheb removes all curses on himself every 30 seconds (starting ~2 seconds into the fight). Curses like Curse of Shadow or Curse of Elements must be constantly re-applied.
Poison AuraPassive aura — deals 196 Nature damage to all nearby players every 6 seconds. Low per-tick damage but constant throughout the entire fight.
Positioning & Kiting

Click image to view full size
The main tank holds Loatheb in the far-right corner of the room (opposite the entrance). This causes Fungal Bloom spores to spawn in the near-left corner, close to the entrance — keeping the spore spawn location predictable and away from the boss. The raid stacks loosely near the spore spawn area. When a spore appears, the assigned 5-player group moves in close to the spore before it is killed so they receive the critical strike and zero-threat buff. All other players stay back from the spore until their group's turn in the rotation.
