There are many weapons that players may use in-game. Previously, characters needed to learn specific weapon skills from Weapon Masters, previously located in Stormwind, Ironforge, Darnassus and Exodar. This was removed in Patch 4.0.3a, and all weapons that a class can use are now automatically learned upon character creation.
Players may wield Axes, Bows, Crossbows, Daggers, Fist Weapons, Guns, Maces, Polearms, Relics (Including Idols, Librams, Sigils, and Totems), Shields, Staves, Swords, Thrown, Two-Handed Axes, Two-Handed Maces, Two-Handed Swords, and Wands. Some classes can Duel Wield, and some weapons have limitation on whether they can be placed in only the Main Hand slot, Off-hand slot, or either.
Axes are a Melee Weapon characterised by a long shaft, with a wide blade on the upper portion, that can be wielded with one hand. Death Knights, Hunters, Paladins, Rogues, Shamans, and Warriors can wield Axes, while Orcs gain an Expertise bonus when wielding them.
Fist Weapons are Melee Weapons that transfer most of the force of an individual's physical strength to the target. Druids, Hunters, Rogues, Shamans and Warriors can wield Fist Weapons. Orcs gain an Expertise bonus while wielding them.
Guns are Ranged Weapons that use explosive force to expel Bullet Ammunition down a long barrel, towards a target. Guns can only be used by Hunters, Rogues and Warriors, with Dwarves gaining a bonus to Critical Strike when firing them.
Maces are Melee Weapons that use a long shaft, with a multi-pronged bludgeoning instrument typically on top. All classes can wield Maces, except Hunters, Mages and Warlocks. Humans gain an Expertise bonus while wielding Maces.
Polearms are two-handed weapons with a blade at either end. Previously referred to as Spears early on in World of Warcraft, they can be wielded by Death Knights, Druids, Hunters, Paladins and Warriors.
Relics occupy the Ranged Weapon slot on Death Knights, Druids, Paladins and Shamans. Previously, each of the aforementioned classes had their own type of "Relic"; Death Knights had Sigils, Druids had Idols, Paladins had Librams, and Shamans had Totems. In Patch 4.0.3a, this was simplified so that all these classes' specialist weapons were changed to Relics. usable by any one of the four classes. These "weapons" are merely Statsticks, there are no spells or attacks that use Relics.
Shields can only be wielded in the Off-hand slot, and can only be used by Paladins, Shamans and Warriors. Of these, only Warriors and Paladins use the Block mechanic; Shamans can use Shields and a one-handed weapon in either Elemental or Restoration spec.
Swords usually consist of a small shaft, with a long, thin, and very sharp blade. These are designed to be wielded in one-hand, and all classes except Druids, Priests and Shamans can wield them. Humans and Gnomes both gain an Expertise bonus when wielding them.
Thrown weapons are weapons that can be thrown at an enemy to cause damage, and then return to the player's hand. They can be wielded only by Rogues and Warriors, with Trolls receiving a 1% bonus to Critically Strike with a Thrown weapon.
Similar to Axes, these are so large that they can only be held with two hands. Only Death Knights, Paladins, Shamans and Warriors can wield these. Orcs receive a bonus to Expertise when wielding a Two-Handed Axe.
Similar to Maces, these are so large that they can only be held with two hands. Only Death Knights, Paladins, Shamans and Warriors can wield these. Humans receive a bonus to Expertise when wielding a Two-Handed Mace.
