So while practicing some bosses I found something a little funny so I thought I would share it. (Was done on PS4)
I was in Chapter 7 II area Eudaimonia, during the Patmednides fight, I was just getting in some damage when I got caught onto the monster's hitbox and was dragged along while they were running away.
After the boss fight was over I reloaded my save before the area to try to do it again and got it to happen again from predicting the boss's pathing when I tried to always keep it in the corner so i can back back into the fight after dodging, by standing in the path you think the boss will take from the corner, and after trying a few times, can really only be 3 (2 if in flat corners of the arena, like in the video) ways since it has to get around you, but can sometimes mess up and drags you until you hit something.
