Can I get the dirty deets on Anasteria?

She’s by far the hardest mob for me in gladiator crucible, none of the other nemesis come close; her damage is wildly unpredictable and super spiky, even with overcapped aether and high phys resist. Still farmable but quite stressful.

Any tips for making her less of a headache?

She debuff you by 50% of all resistances.
