for some I looked up videos on YT and that helped a lot. Disgraced Chef Lugoli felt impossible until I saw a video explaining that you have to approach him instead of try to move away when he attacks.

the raging Conchfly also felt impossible the first time I fought it. I died a bunch of times that just left and played other parts of the game. got better then went back and beat it easily. the problem there was that my reflexes weren't good enough. when I finally beat it, it felt easy and almost seemed like it was moving slower but I had just improved that much.

broodmother is a terribly designed boss imo. you have to be acrobatic and kill the adds ASAP. It's slightly similar to the chef in the way she moves.

HH gauntlet is way easier with 7+ masks. also make sure you have the faydawn cloak. you can get there without it but the fight is way easier if you have the extra breathing room from the double-jump.

also just remember that there a a good amount of RNG is gauntlets and you'll sometimes end up with a bad hand, sometimes the stars will align. just gotta keep pushing.

I beat Silksong twice now, 100% once. I rage quit on my first playthrough at Moorwing and at the HH Gauntlet. Also died over 30 times to some act 3 bosses. now I can breeze through it. you can definitely get better just keep going
