Bone Serpent

Bone Serpents are the strongest non-boss, non-hardmode burrowing enemies. They follow the Worm AI. Bone Serpents, like all other worms, are immune to lava. They are also immune to the Poisoned and the On Fire! debuffs.

The best way of killing one is the same as killing any other worm, by using weapons that can hit multiple segments at once They are not restricted to the The Underworld and can follow the player out.

Bone Serpent consists of 14-20 segments in total. It drops loot from the head segment, which can get stuck in blocks, requiring a bit of digging to retrieve. It can also drop into lava, so be careful it you are trying to collect its coins or its banner.
