It doesn't seem like Turtle is helping them this time. How does Richie rescue Bill and injure It?
"Bill crushes It's heart between his hands, finally killing It."
I realize It was severely injured at this point but that doesn't exactly sound like using the power of belief to harm It. Bill is an ordinary human, right? If he can use his bare hands to physically harm It, why won't Mewtwo's Shadow Ball work?
Richie mainly just catches It completely by surprise (she thought that Bill was the only one who really had the strength of mind to oppose her, and his death would scatter the rest) and serves to give Bill some moral support. As for how Bill hurt It, she was pretty damn banged up at that point due to losing the ritual, it was made pretty clear she only fought back at that point because she was hurt enough that she couldn't hope to win no matter what she did so she chose to stand and fight because it was slightly less hopeless than stumbling away and having even less energy to fight back when they caught up, and I guess being that badly injured let Bill finish her off, although technically she still probably didn't outright die <_<
