The Horseman's Blade

The Horseman's Blade is an auto-swinging sword which summons homing Pumpkin heads after striking an enemy. It is currently the second strongest sword in the game, being beaten only by the Terra Blade by 5 base damage. However, this weapon´s ability makes it so that it does more damage per swing than the Terra Blade. Despite it being called Horseman's Blade, it drops from Pumpking.

Trivia

 * This weapon is a reference to "The Legend of Sleepy Hollow" by Washington Irving, and the famous Headless Horseman, and is depicted carrying a Jack-o-Lantern under his arm (instead of his own severed head) in a famous Disney cartoon. The Horseman would also throw the Jack-o-Lantern at his victims and thus the projectile ability.
