suffer
sorry, it's been a long time since I've played this game. I remember this part being annoying but I don't remember exactly how I beat it, so details could be off. You just kind of have to play it over and over until you can do it fast enough, I think I got through that by like the skin of my teeth. If I remember right, the spider keeps moving when the dialogue box pops up when you pick up the shard, so you just kind of have to get through the dialogue box as fast as possible and start moving IMMEDIATELY after it closes, and not get caught on anything while you're running away. One moment of getting stuck will kill you so just have to know your path super well and can only really do that by trying it over and over again.
good luck.
