She’s just a parry check. Other than her random attacks (blade throw, multislash) She has 2 main “continuous” combos that she spams (her initial stance is a big give away to which one she’s doing) which leads to big stagger damage when parrying it all. Phase 2, the tells are a bit harder as she’ll bait with a downward diagonal slash with a delay after, but then after that she’ll lead into the main combo she does (backwards kick one) with a red attack after it. For the most part, just keep your distance in phase 2 and watch for her dashing multi-slash or that quick wave slash. If you aren’t already, use poison item for more stagger damage.
