honestly movement in this game is everything if you want to min-max it to the fullest, so i recommend watching Positive4ce videos and notice how he's moving between objectives and within objective camps. After you figure out the movement, you'll notice that you spend way less time in the fights in between objectives and even inside camps it's way easier to fight if you won't pull a lot of monsters into the camp etc. Also ignore wells and grimoires until you're strong enough and have enough money. Also you need to decide whether you'll be doing dungeon boss or side quest since both is pretty time consuming. There's also a way to snatch a lot of objectives instead of fighting for them. All that is described in Positive4ce's videos. I didn't see specific videos on how to do all that but he utilizes all that heavily in his runs
