Polearms

Polearms are, along with Spears, the largest weapons in the game with the most reach. In Diablo II Polearms are unpopular due to their relatively low damage and slow swing speed. They aren't even that good for Barbarians to use with Whirlwind, as they have much lower damage then the top blunts or spears. They are improved somewhat at higher levels in the Expansion, however.
Polearms have been used for centuries as weapons of destruction, though their roots stem from humble farming tools. Derived from the spear, the axe, the scythe, and the hammer, polearms are any combinations of those, and come in all shapes and sizes, from the rudimentary war-scythes to the devastating bardiches and glaives. The polearm can easily strike beyond the range of even the largest swords and axes. Wielding such a weapon requires great strength, skill, and the use of both hands. The Barbarian is the expert in polearms, and his masteries skills tree includes a Polearm Mastery skill.
