Because of the spell that Boa had cast before the meeting, she landed hard and got the wind knocked out of her as she hit a rockier bit of embankment. Her sword had been thrown as well, and she made herself focus on that as she gasped for air. It could've been worse, a lot worse; if she hadn't done her feathersteel spell, she would've needed stitches.
But that was smart thinking she'd be thankful for later. She made herself breathe, made herself find her sword. Inwardly Candy chastized Boa, reminding her that her moronic compassion was what had done this. After a few gasps she got up, running to where she saw the sword glinting in the gravel.
