Headless Horseman

The Headless Horseman is a Hardmode, post-Plantera enemy that starts to spawn after wave 8 of the Pumpkin Moon event.

The Headless Horseman is a very fast and dangerous enemy that rushes at the player and deals large amounts of damage. It is an exceptionally dangerous enemy due to its fast speed, high damage, and immunity to knockback. The Horseman's only attack is to charge forward and do a low, but quick, jump to reach the player.

Tips

 * Due to its size, it cannot fit through 4 tile gaps or lower and can be taken out easily with ranged attacks.
 * Due to its immunity to knockback, it is ill-advised to attack it with close-range weapons since it can easily overwhelm the player.
 * Similar to most of the Pumpkin Moon enemies, making an arena where you have plenty of space to fly around in can make it easier to take down or you can make some wood platforms in a decent spot in the air to stand on and fire on it from above without fear of it reaching you.
 * Its immunity to knockback can be used against it with weapons that do continuous damage such as the Inferno Fork.

Trivia

 * The Headless Horseman originates from a short story published in 1820 called "The Legend of Sleepy Hollow" By Washington Irving.
 * Despite being headless, it wears a pumpkin.
