A modified spear potentially has further reach than any other weapon in existence. Increasing the shaft to a length of 2.3 metres means Longspear regiments in the Xilan forces can, especially in defense, stab at enemies with impunity. While still vulnerable at range, a group of Longspears can charge a path through enemies or defend a choke against enemies who outnumber them.
All of Xilan, except Japan and Silla.
Longspears saw significant use in the Xiong-Zhangat wars by Xilaroi/Xiyi, as well as subsequent smaller conflicts, but eventually were made obsolete in their role at the head of the Yi army by the Silent Guard.
