Flawless Victory

This is rather easy to do theoretically. But when you have 20+ other people trying to do the quest.. it's actually quite impossible to SOLO one of the behemoths. I've been trying to do this achievement for the past hour.. I'm having no issues avoiding the stomp or boulder.. the issue is other people attacking my target. Just try to move your target away from other people, or wait until it's quiet on your server.

To avoid the stomp if you're melee, simply jump as you're running away and you won't get hit. Avoiding the boulders if you're range means moving if a black shadow appears where you're standing.

Also, to clerify something because I know it had me confused in the beginning.. this achievement requires you to solo kill a Molten Behemoth in Molten Front, NOT the Fiery Behemoth found in Sethria's Roost.

FINISH HIM!

The hardest part of this achievement is actually getting people to stop helping you kill the mob.
