Arrows are items added in Update 0.3.3. They are used as ammunition for the secondary weapon, the bow. Arrows can be crafted by the player using a crafting table.They can also be dropped by Skeletons, along with Bones. Due to the fact that arrows are also dropped by Skeletons, some players prefer to save the crafting ingredients and kill or farm skeletons instead. 2  When shot from a bow, they have significant knockback as well. 3  Shot Arrows do not affect Endermen, as they would teleport away right before the arrow touches them.
