They Burn, Burn, Burn

Easy Achievement at Level 120 Battle for Azeroth and beyond...

1. Heroic Difficulty

2. Stand on Sol's platform, aggroing boss. Do not attack.

3. Go do something else for a few minutes.

4. Plenty of fireblooms flowers have spawned, now jump over the rings of fire, baby.

5. The Achievement will Pop once you've jumped over five rings of fire.

6. If you didn't get it, don't fret, just try it again and don't kill boss till you get it. Once achievement pops, kill boss.

7. ?

8. Profit. Achievement Completed.

I did this achievement with a group last night. I am surprised no one on Wowhead has written the following basic advice yet:

One, DO NOT interrupt Parasitic Growth. Archmage Sol drops the fire flowers only in the fire phase, and interrupting Parasitic Growth causes her to switch phases. You want to keep her in the fire phase until there are five flowers out there.

Two, you do not actually have to time your jumps if you just spam spacebar the whole time. As long as you hammer that key continually, you still get the credit for jumping over a circle even if you land on the ground just as it goes under you. So don't worry about mounting, disengaging, etc. - just jump, jump, jump, and do not stop jumping until you get the achieve. Do not press any keys other than the spacebar.

Other than that, the other posters' advice is correct - stack up and hold DPS until all five people get it.

NOT possible to do this on Mythic difficulty. Only Heroic.
