Mace

An advancement of its poor cousin, the club, the mace is a bludgeoning weapon with a metal head outfitted with flanges, spikes or knobs. Used on numerous worlds, including Britannia, Earth and Serpent Isle, maces appear in Ultima I,  II,  III,  IV,  V,  VI,  VII,  VII Part Two, and  IX, as well as in the Underworld Series.

Description
Maces and cudgels have been in service since before the coming of Mondain. Favored by priests and clerics, these heavy bludgeoning weapons can cause a foe's bones to splinter and break -- thus making it particularly useful for creatures such as skeletons. Respected for its effectiveness and often cheap cost, a mace often provides a study defense for those not trained greatly in the arts of war, and has long been used by mages and  druids. In Ultima VII and Ultima VII Part Two, maces have damage rating of 5 and a range of 2. In Ultima VIII, they deal between 4- 14 damage per strike, and in Ultima IX they deal between 5-11 damage per strike.

Magic Maces
Although not as common as magical swords, a number of enchanted maces are known to exist. Among these number the jeweled Mace of Unsurpassed Damage; the Mace of Undead Bane; the Cudgel of Entry, a utilitarian weapon with enhanced potency in knocking open doors; and the fearsome Slayer, which was said to have a grim sentience within it that thirsted for bloodshed.

Trivia

 * The association with maces and clergy has a long running history in fantasy role-playing games, and may stem from historical Christian beliefs which forbade the use of weapons capable of spilling blood - an attribute which has been commonly been assigned to the famed warrior cleric Odo of Bayeux.
