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.

The best way of killing one is the same as killing any other worm, by shooting the floor with a harpoon which will almost instantly kill it or, by using weapons that can hit multiple enemies simultaneously like the Blade of Grass, a flail, or the Vilethorn. When fighting them it is recommended to have a lot of potions, end game armor and weapons to be able to stay alive for extensive periods of time. They may also rise out of The Underworld into the cavern layer during night time and their spawn rate is increased.

Bone Serpents are immune to the Poisoned and the On Fire! debuffs.

It drops loot from a head segment, therefore it can get stuck deeply in blocks.

Bone Serpent consists of 14-20 segments in total.

History

• 1.1: All segments now share a life counter, instead of individual life counters for all segments. Previously Head, Body and Tail had 120, 150 and 200 health, respectively.
• 1.0.6:
  • No longer drops Sunfury and Flamelash, which are found in Shadow Chests instead.
  • Bone Serpents were given a new death sound.
  • Their hit-box has been recalibrated.
• Pre-Release: Introduced.

Bug: Like the Giant Worm, sometimes they spawn without any body segments, resulting in a floating Bone Serpent head.
