My only tip is taking in all the information you get during the game (other than the story, that is optional). Your mind is a better weapon than any bow and arrow. Remember weak points of your enemies, scan all the new things you find, remember the different herbs and always, always remember what you yourself are weak to. Unlike mist games, your character isn't an OP robotic war machine that barely flinches after a hit. You can die easily, and so can your enemies. Remembering weaknesses and strengths and using them to your advantage will help a lot, more than you think.
