Bestiary is world specific, meaning if you take character A to world A, kill 50 blue slimes, then make a new world B and enter that with character A you do not have blue slimes in that world B's bestiary. Additionally character B joins world A and has access to the blue slime entry without having killed one. I feel like it would be better served if the function were reversed and bestiary progress is per player not per world.
