Jester's Arrow

Jester's Arrows are the strongest version of arrows that are similar to the Unholy Arrow which can pass through any amount of enemies. These arrows may only be found in chests found underground.

These arrows cannot be retrieved as when shot they fly creating sparks and--after hitting a block or after flying so far--explode, emitting a small firework style blast. (This does not cause damage to blocks!)

Like other weapons that emit light, they could also be used to check for caves.

When shot, these arrows can pass through any amount of enemies and the magic explosion can pass through blocks, making them good for defending against armies while indoors.
