The World Revolves Around Me

Easy Solo for Level 120 Battle for Azeroth, Level 60 Shadowlands, and beyond...

1. Normal Difficulty or higher.

2. Begin Fight. Minimal damage for now.

3. Purple Balls are going to roll around the platform. Stay as tight against the boss as possible. Do not run into purple balls.

4. Eventually boss gets shielded and you have to kill the other adds, kill them, but do not run into the purple balls doing that. Once adds dead, boss is attackable again.

5. Once you get to 9+ purple balls rolling around the platform, you are good to kill the boss.

6. Nuke Boss.

7. ?

8. Profit. Achievement Completed.

Just did it solo as Blood Deathknight level 60 item level 243.

Just do not touch the purple balls.
You can wait.
You can stand in the fel fire.
Do whatever you want, but do not touch the balls.

For this achievement you will want to have your entire raid group stay in melee range of the boss and only detonate the [spell=246779]s that spawn in melee.

Once 9 Diabolic Bombs are active, nuke the boss and you'll get the achievement.
