Unholy Arrow

Unholy Arrows are Arrows that have a piercing effect, allowing it to penetrate five monsters (Jester's Arrow have a similar effect). Against multi-section monsters, a single Unholy Arrow can damage multiple sections.

Unholy arrows are obtained through crafting worm teeth and wooden arrows, while using an Iron Anvil. They are also dropped by the Eye of Cthulhu and can rarely be found in chests underground. Unholy Arrows can also be purchased at night from the Arms Dealer for 40 copper each if you have defeated the Eater of Worlds.

Patch Notes
1.0.5 : Unholy Arrows can now be purchased from Arms Dealer after killing the Eater of Worlds.
