An arrow is an item in Expedition. It currently serves as ammunition for the bow and is made with one arrowhead and one arrow shaft. This item is not in your inventory, but your quiver bar. (right above the health, hunger and thirst bars) When crafted, 3 Arrows are made.
Arrows can not be placed on the ground and will not fall on to the ground upon death. Arrows can not hit through armor, but you can hit players in the arms or legs.
