Marrow

Marrow is a rare drop from Skeleton Archers deep underground. It turns any suitable arrow into a bone-like arrow that fires at an extremely high velocity in a straight path. Fired arrows do not get their effects, if there is any, and once fired the arrows cannot be retrieved. If planning to use it cost-effective, you should use wooden arrows since the effects won't apply. If you want to maximize damage output per shot, then using your highest damage arrow type is ideal (Venom arrows are damage-effective since they cost very little, requiring only wooden arrows and Vial of Venom to make).

Trivia
• Marrow is a substance found inside of bones.
