Fel Turkey!

Place world markers in a line and have your ranged dps and healers stack up on them so that Goroth spawns the [spell=233021]s in a straight line pointed towards him. Once someone is marked by [spell=233279] they will have to go behind the pillars so that the star collides with the [spell=233021]s and destroys them.

Rinse and repeat until the tracker goes white and then you can kill the boss.

For anyone trying to solo this at 120:

I don't think it's possible to solo yet because you don't get enough spikes. I only got to around 20 destroyed by stars before he berserked. That being said, judging by how it went solo you should be able to duo this no problem as long as one of the people has a pet, or use 3 people with one person tanking.

You also need some kind of healing or damage mitigation because you're inevitably going to eat at least one full round of infernal burning, which you're supposed to block with spikes.

Easy Solo Achievement for Level 70 Dragonflight Pet Classes, Level 80-100 Pet Classes World Soul Saga & beyond...

1. Normal Difficulty (though I did it on Heroic)

2. Achievement tracker should turn from Red to White upon satisfaction.

3. Begin fight

4. Aggro to pet, and face boss towards the wall where he spawned from. Do not attack boss after initial aggro.

5. Now begins the fun. Inferno Spikes spawn throughout the fight. You have to stay away from them until Shattering Star with the Green Arrow emits from the boss or else they will be destroyed early.

6. I also counted manually just to be safe. Count 30 destroyed Inferno Spikes by Shattering Star, some reports have the achievement tracker not turning white, so you have to make sure you have 30.

7. I did 32 just to be safe.

8. Once you have enough, nuke boss.

9. ?

10. Profit. Achievement Completed. Enjoy your Fel Turkey.
