The Blood Eel is a flying Hardmode enemy that can be spawned by fishing in water during a Blood Moon. When the bobber dips and the player attempts to reel in a fish, a Blood Eel or another enemy has a chance to spawn within a few tiles of the bobber in place of a fish. Its behavior is rather similar to that of the Wyvern, though it moves considerably faster.

It is one of the few entities that can be detected by the Lifeform Analyzer or its upgrades. The Blood Eel requires 25 kills to be awarded completion of its Bestiary entry and corresponding banner, as opposed to the usual 50 kills.

  • The Sonar Potion will detect if a Blood Moon enemy is about to be hooked.
  • Using the Chum Caster will greatly increase the chances of hooking Blood Moon enemies.


  • As with any multi-segmented enemy, piercing and explosive weapons can strike multiple segments at once, dealing several times their normal damage.
  • The head of the Blood Eel has lower defense than its tail or body segments, making it more vulnerable to damage as it charges the player. However, the head also deals twice the damage as the rest of the body on contact, making it risky to face the Blood Eel head on.
  • The Blood Eel can be easily dodged using the Shield of Cthulhu. As the Eel comes in to attack, perform a dash away from or under the Eel to avoid being hit.


  • The BestiaryBestiary entry for the Blood Eel: "A large, worm-like demon, dripping with blood - both its own, and its victim's. It's a bloody nightmare of a fiend!"
