She has devastating attacks and may one shot you with her ice missles( sprint away, don't roll, because the last one will get you once the iframes go out, she won't use them all at once). You want to play it safe at hit her once or twice, back up, because her speed and aoe is good. Let her attack, and when she tires, (her stamina recovers really slowly, she will run out of juice after a bunch of attacks) that's when you get her. Best time to living weapon is when her stamina is out and you hit her, causing her to stop and cast a spell to recover her stamina. You can stagger her and you can do critical damage with a Living weapon. There are plenty of chances to spam her with various ranged attacks, as sometimes she will slowly walk to you instead of sprinting, esp if she intends to melee. You can unleash a guardian spirit or a bunch of kunai. be wary of how fast she recovers from attacks. Her combos are small, but the window you get to hit her, after she does her two or three hit is small. You may get tagged again if your combo is large.
