Bolt Throwers are simply larger versions of the crossbow, able to fire heavier bolts over greater distances. The Bolt Thrower remains an important part of the Dwarf arsenal because it can be built and maintained cheaply and is accurate enough to bring down monsters such as Wyverns or Trolls with a well-judged shot. This metal box set contains 1 Dwarf Bolt Thrower and 3 Dwarf Crew.
