Crossbow bolt
Crossbow bolts are a necessity for all players who use crossbows. They serve the same function as arrows but are used as ammunition for the crossbow instead of the bow. They can be stacked up to 64 in the inventory.
These bolts can also be found in chests in many structures, such as Uruk Camps. They can also be bought from a variety of traders, such as the Uruk-Hai Trader, Blacksmith of Rohan, or Blacksmith of Gondor.
Crafting
Crossbow bolts can also be crafted on a normal crafting bench with an iron ingot, a stick, and a feather. They are crafted in groups of four, just like arrows.
