I've tried that too but with enemies being able to do 80+ damage I usually die in a few hits. As far as I can tell there's no way to use or equip items or grind my stats, which would be my usual response to an enemy that kills me in seconds.

I have. Tends to work pretty well on regular enemies but for bosses it merely makes a dent and it feels like I either have the option of having my entire poise bar deleted and get a 90+ second stun, or having my entire health bar deleted and dying anyway. If the intent is that you're supposed to oneshot bosses before they can even hit you, I feel like the game might need better explanations as to the how.
