Step 1: kill 3 of the 4 corruptions
Step 2: Either stand in a dead corruption spot for hook debuff or dance back and forth across the middle of Deathwing's spine to prevent him from rolling
(for the Maybe He'll Get Dizzy... achievement force Deathwing to roll 4 times in the following order left, right, left, right, then complete this fight normally)
Step 3: wait for 9 bloods to spawn and then kill them
Step 4: kill a corruption that is up to spawn an Amalgamation - you must also now be dancing back and forth
Step 5: make sure the Amalgamation gathers 9 blood debuffs by walking over them
Step 6: Kill the amalgamation near the front of Deathwing, at this point the Amalgamation will go Nuclear and blow up, if successful, the plating will pop up.
Step 7: Kill the burning tendons to remove the plating and move forward
Step 8: repeat steps 2-7 two more times and you will win
Congrats on defeating the Spine of Deathwing and getting the Maybe He'll get Dizzy... achievement!
