How to Beat Kui Yanyan, the Deranged

[1] Stay Close

Backing off gives her room to throw daggers and reset her strings. Stay at mid range, block her first swings, and hit back in between.

Stay Close

[2] Read the Flashes

Watch for the flash and not her arm. Parry the blue flash and dodge the red flash.
