Guild Wars 2

Any tips for accomplishing this as a fire elementalist? I am having some difficulty subduing her. She seems to move around and regenerate quite a bit. Any help would be appreciated.

Until you give us more about your setup (traits/weapon/utilities/level) it’s hard to give better advice. I rolled through her like all PvE with D/D, but I’m also level 80 and in exotics. You might have different circumstances.
