The Truffle Worm is unique in that it is only used for summoning Duke Fishron.Most critters that are invertebrates (insects, scorpions, snails, worms) can be used as bait, and must be caught with the Bug Net, Lavaproof Bug Net, or Golden Bug Net.There are several items that can serve as bait, and they must be obtained in different ways depending on the type. Even when the player does reel in a fish, there is only a chance that the bait will be consumed. It is not consumed upon the player casting the line or the line being reeled in with no catch. The bait item is only consumed once the player reels in the line with a catch on the hook. Fishing poles will cast their lines with no baits, but there will be no 'bites' and no catches. When a fishing pole is cast, at least one bait item must be in the player's inventory otherwise, nothing can be caught. Bait is a group of items that is mandatory for fishing.
