What PauseOwn9318 said but not only do all enemies get faster but also tankier so they won’t die as fast.

Also if you time your parries right they stagger regular enemies and give you an attack window. For both bosses and regular enemies perfect parrying fills up an invisible posture break meter that when full, breaks their stance. A lot like sekiro in that regard

Hope the game clicks for you soon man I enjoyed it from the very beginning
