Bone Serpent

Bone Serpents are burrowing worm-like enemies that spawn in The Underworld. They are immune to lava as well as the Poisoned, On Fire!, and Cursed Inferno debuffs. Bone Serpents consist of 14-20 segments in total.

Tips

 * As with most worms, weapons that can hit multiple segments at once are effective. Some effective weapons are the Vilethorn, flails and the Crimson Rod.

Trivia

 * Bone Serpents are one of the few pre-Hardmode enemies that don't get stronger upon reaching Hardmode in an Expert or Master world.
 * Sometimes a Bone Serpent can be seen leaping in the lava in the background as ambience.
