Halberd

A halberd is a polearm which combines characteristics of both a spear and an axe, allowing its wielder a long reach in a melee. Such weapons appear in Ultima IV,  V,  VII,  VII Part Two and IX, as well as in the  Nintendo port of Ultima III.

Description
Halberds afford their users a great deal of distance between them and their enemy, although as weapons they can be heavy and cumbersome. Commonly used by guards and paladins, the halberd has long ranked as one of the most powerful mundane weapons available to  Britannians.

Magic axes were listed in Ultima VII and Ultima VII Part Two as having a damage 10 and a reach of 3. In Ultima IX, a halberd does between 55 - 85 damage.

Trivia

 * In the Nintendo port of Ultima III, halberds replaced +4 axes  in the hierarchy of weapons - and could be bought at Dawn for the same price as enchanted axes in the original PC version of the game.
 * In Ultima V, the additional range of halberds allowed them to strike enemies through walls.
