just "beat" the game today but there's still a ton I haven't done. I ended up beating Phantom as well after the main boss because originally I had no idea how to even get to them and would never have bothered to spend time figuring it out without a guide. I really don't care about act 3 or steel soul or any of that shit I just wanna fight the fun bosses and explore a couple more areas. I'm going through Bilewater right now so I can get the key for what I'm assuming will let me access the First Sinner fight, which I've heard good things about. Are there any other optional fights which shouldn't be missed? That's what I want to do before I finish with this game
