Hi I'm going to be Hosting a Pathfinder group soon. I have the core rule book but I dont have the money to buy the beastiary(sorry if its not spelled right). I still have my beastiary from dnd 3.5. Are they similar enough for me to just use my old beastiary. Would it be unbalanced. I dont care about organized play so that's not an issue for me. I have a beginner box so up until level 5 I have enemies to use. So its not really urgent.
