Unholy Arrow

Unholy Arrows are Arrows that have a piercing effect, allowing it to penetrate three monsters (Jester's Arrow have a similar effect). It will travel through multisection monsters, as each of their sections is considered its own NPC.

Unholy arrows are obtained through crafting worm teeth and wooden arrows, while using an Iron Anvil. It is generally considered easier merely to hunt monsters, such as Eye of Cthulhu
