Jester's Arrow

Jester's Arrows are one of the strongest variety of arrows. They are similar to the Unholy Arrow, but can pierce through any amount of enemies within its maximum range, and therefore have no limit in total damage per one arrow; accordingly, they are best reserved for worm-type enemies such as the Eater of Worlds and The Destroyer. These arrows may be found in chests in the Underground and Cavern layers or within the Dungeon, and can also be crafted.

Hellfire Arrows and Cursed Arrows do more damage than Jester's Arrows, but they can not pierce multiple enemies and therefore can be worse in total damage inflicted per one shot.

Jester's Arrows will create sparks while flying. After hitting a block or traveling a certain distance, they will explode in a firework effect. This explosion does not cause damage to monsters or blocks. Like other weapons that emit light, they can also be used to check for caves.
