Easy Solo Achievement for Level 70 Dragonflight & Beyond...

1) Mythic Difficulty.

2) After Lord Stormsong is defeated, jump in and swim down much deeper than you usually would on the way to the next boss.

3) You'll see these purple void balls floating about, swim into one, you'll get the debuff.

3b) Do not swim too far down or you will die very quickly.

4) Swim up to Vol'Zith's platform and nuke boss.

5) ?

6) Profit. Achievement Completed.

Just solo’d this. Super easy. Swim down far enough after the third boss to see the little purple orbs (your screen will turn purple around the edges.) Don’t go too far or you will die. Swim through the orb and you will get the debuff. Then just kill the adds first before him and then the boss and you get the achievement. Easy peasy!

This can be done with less than 5 people :) Just completed with only 3. You still have to make sure that everybody has the debuff but it can be done with less than 5. Useful to know when you can't find a full group like me!
