Siege of Orgrimmar Boss Guide
- Whenever Immerseus reaches 0 health, he splits into P2
- In P2, each black add killed or blue add healed reduces his Energy by 1 (starts at 100)
- When P2 ends, he restores health equal to his Energy percentage, and P1 repeats
- Reduce his Energy to 0 to defeat him
Phase 1
Swelling Corruption
- ~12s into each P1, boss applies [Energy / 2] stacks of Swelling Corruption to himself
- Attacking into Swelling Corruption spawns an add AND puts a stacking 6s DoT on you
- DoT deals exponential damage. 1 stack = 2.5k dmg/sec, 7 stacks = 500k.
- (3 stacks is safe, 6 is max with defensives)
Sha Bolt
- Puddle on each player every ~10s
- 5yd spread minimum (but not too far, the whole raid wants to be in 1-2 sections)
- All puddles get sucked in at start of P2
Swirl
- Dodge moving waterspouts (see red circles)
- Dodge rotating breath (rotates over 40% of the room)
Phase 2
The Split
- Slimes shoot outward, then attempt to travel back to center
- Spread out to kill as many blacks as possible
- Standing on a slime as it dies gives +25% dmg
- Slimes can be stunned, rooted, slowed, knocked back, etc.
Sha Pool
- Center pool expands in P2
- Standing in it shrinks the pool, but causes a stacking DoT
- Everyone helps soak it down
