The Vilethorn is a ranged spell that can be found upon breaking Shadow Orbs. It inflicts 10 Damage, has average speed, and costs to use. It creates a piercing spear of thorns that go through walls and have the potential to strike multiple hits upon enemies. It can be very useful to defeat the Eater of Worlds and other large enemies such as the Bone Serpent and Eye of Cthulhu, but it's generally more effective to use a Flail such as the Ball O' Hurt to defeat these enemies, especially if they have a high defense.
