How tho? There's like no window to pull it off, and you have to be super close. The few times I pull it off she either dodges or swings through it
If you having that much trouble, get the elevator key that goes straight to the boss and take a bat or a knife
the key is to do structure damage
but you can just cheese her first form, run around and keep your distance until you see her full string, you only need to evade the last move so get close when she's about to do it and just weave, you will get the punish, you have to evade the last attack to get the combo the palm strike causes a lot of structure damage so you can end the fight quick
Up, Down, Up, Down, will dodge her entire second string, unlike the catch weapon skill to throw the knife back at her in the second phase if you can't dodge, remember when she jumps in the air to dodge with the left or right stick not up or down, and when she charges remember not to dodge until she starts coming toward, you can do big combos when you evade those attack use palm strike to cause a lot of structure damage
