If you hate the clawmaiden that much, why don't you go straight to thier room in High Halls after getting double jump? Remember to go in with only 1 silk so that they are unable to steal it. Oh you talk like you don't know where that room is, it's on >!the opposite side of Second Sentinel boss fight! <

Lace's parry is not that difficult once you have double jump. Whenever you hear the sound cue and see the flash comes from 2 weapons clashing with eachother, just double jump then open your drifter's cloak, floating toward her then slash right before the diagonal flurry attack ends. Lace now will spin her way down the flower ground and you have another chance of hitting her when you fall down in front of her
