I've gotten a few chests while fishing and always wonder if the later the world came out, the better items you get from fishing. I just want to know if the value of the items you get in the chest has to do with the world your in, or if it's random.
the higher level required to enter the world, the higher level items, higher chance of rare drops like pets, and the higher the gold in the chest. This is just what I have noticed. The gear is always gear dropped or bought in that world.
