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.
