Bolt's
A bolt or quarrel is the ammunition fired by crossbows regardless of the weapon's size. Bolts look similar to arrows but have shorter shafts, and are tipped with a conical or pyramid-shaped iron head, thus causing piercing damage. Light and heavy crossbows can fire one bolt per round. The bolts are weightless with respect to encumberance.
