Blood Eel

The Blood Eel is a flying Hardmode enemy that can be spawned by fishing during a Blood Moon event. 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 blocks of the bobber in place of a fish. Its behavior is rather similar to that of the Wyvern, though it moves considerably faster.

Tips

 * As with any multi-segmented enemy, piercing and explosive weapons can strike multiple segments at once, dealing several times their normal damage.
 * Using a bow or repeater with Jester's Arrows or Holy Arrows is a good way to kill the Blood Eel.
 * Other useful items for killing Blood Eels and other worms are the Shotgun (with Explosive Bullets), the Nimbus Rod, and the.
 * The Life Drain, obtained from Crimson Mimics, is also an extremely powerful choice, as it can suck life out of many segments as once.
 * 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.
