I run with Bowl of Orrian Truffle and Meat Stew and stay back so I can get shadowstepped to. I use blocks and reflects to prevent her from hitting me (and therefore the rest of my team) with her shadowsteps.
Occasionally I will encounter a party member who doesn’t understand that she shadowsteps furthest target (even after being told) and will run away when low, trying to wait so they can heal up. That is the biggest mistake you can do in this fight. if you’re low on health, stand mid-range from her, not far range. Make sure someone else is behind you, and do not stand in her flourishes.
In fact, I rarely go melee in this fight, if I ever do, it’s to blind her or just in mid-melee range so she’s close, but not too close (so the zap-attacks will take off her stacks and I won’t be in range of the flourish).
I also make sure I stealth if I ever have to go next to her to res someone. With Prismatic Understanding, I either get Prot, Regen or Aegis every second, which makes it really useful for ressing people in sticky situations.
I also run Lyssa runes on my current armor set, so if I am ever running around with 20 bleed stacks, I’ll use Mass Invisibility to cleanse myself, aide low teammates, and gain all boons.
