since i found out there is a def cap (more then 3 procs of 200% is useless and she still deals 2k dmg on ur cards) attack down works actually pretty well if ure trying to lotsa rounds on her. u can easily get her autoattack down to 50 and her crit to 500 wich is nothing compared to your 20k+ hp.

but i dont have an great attack downer. i tried using an gsr with +30% but she dies earlier to fast.

HuangLong with unleasher and nulli is still the best tho.
