Firearms
From CLOKwiki
Firearms are a fairly recent invention, employing explosive powders to propel metal shots at high speeds. They are quick and easy to fire, causing little fatigue and allowing them to be fired at melee range, though they require powder as well as ammunition, making them more costly per shot and complicated to manage than other ranged weapons. Exploration into explosive powders is still new, and firearms are generally less powerful than their other ranged weapon counterparts.
