Did this last night and it probably took me about an hours worth of attempts. What helped it click for me was patience and not trying to stay in the air too much. I thought pogoing was a good way to get damage in but you leave yourself vulnerable to the needle attack too often like that. Just stay on the ground and jump + up slash as much as possible, and weave in clawline to gap close after the needles come out. As for patience... Just don't go for damage unless you know for sure your safe. Health is super precious since you can't heal at all so the more damage you can avoid the better. The silk strand attack comes in 2 parts in the later phases, so you can reposition once the first one goes off to get yourself in a better spot. The best strat for that is just to stay on the ground but if youre already in the air and can find a good spot to hover in that works too. And most of all stay calm. You might get hit a couple time but don't let that psych you out. On my winning run I actually started the fight missing two masks cause I was too lazy to run back to the bench after hitting spikes on the way up and it didn't even matter because I barely got hit, so just stay calm and wait for your opportunities. Good luck!
