An almost kill for these brave souls. The fight has graphical issues, but it's otherwise a cool encounter. Take aways: stand in those crystal things during shadow storm, tank the sisters far apart and taunt switch like dragons in EN - face them away, don't stack fire debuffs, and kill all kill-able adds asap (this attempt didn't see them for some reason). If you get the wall of walking adds, stun them and run by. Repeat.
