So I've managed to get Holy fist and I used the jester badge and the prince badge with the river guy, the jester one gave me treasure and gargoyles, the princes one just seems pointless...: I was mad about it so I killed the river guy. I also don't have the knight badge since I gave it to the jester, and in other answers they say you need to have kept it. Am I basically screwed at this point cuz I've progressed a lot otherwise, but I want to upgrade my weapon with Blood crystals.

Yeah, you're screwed. You're gonna have to reload an old save file from when you still had the knight badge. If you overwrote all saves where you still had the knight badge, there's nothing that can be done about it and you'd have to either reload an old save file (making you lose a lot of progress) or just start a new game.

You could save Bread! The Knight Trapped in the cave! The way you can save Bread is to just Seduce him and don't kill him! After he goes with you back at the tavern he can give you random items from the game every game day pass
