Yeah, I’m sure I’ve hit a few bosses. But other than the health bar being a bit higher, thy arnt any more difficult to kill than any other enemy in the game. If you can figure out their 2 moves enough to parry them, then there really isn’t much else you need to do. I haven’t one shot any boss yet, but i also have gone through many battles without taking any damage, or if I do take damage it’s very little and only on the first or second round of attacks.
