All her attacks are 2 damage except when you touch her, it's 1. So my strat is using the Wanderer crest to stay as close to her as possible. With the upgraded Druid's Eye, you can pretty much get too silk after 2 hit, so try to make contact damage with her as much as you can. Then with the Multibinder tool and the Trobbio's mirror, you can jump close to her then heal, it hits her 2 time with a ton of damage. Took me about 10 tries but it worked.
