Batmud: Polearms skill

Weapons ranging from long spears, to halberds and pikes, all
fall under the category of polearms. While not as commonly seen
as a sword or an axe, they are still effective weapons. Due to 
their size and abilities they are most commonly found in large
organized armies. Ineffective for close in fighting and skirmishing,
they are prefered usually for large scale battles involving
hundreds or thousands. They are effective when used in great numbers,
being able to create an impenetrable wall. Their great length also
makes them ideal for either using on horseback, or using from the
ground to counter foes on horseback. A great deal of skill is 
required to use these weapons effectively. Knowing when to feint
and thrust can make all the difference in sticking your foe
in the chest, or thrusting into open.
