There are many types of weapons. The most commonly used are bladed, like swords, or sharp and heavy, like a mace. Using standard weapons requires the Swordplay skill. It is also possible to use various types of bows to fire arrows, possibly poisoned, at your foes - even from distance. The use of bows requires specialist skills, like Forestry or Weaponry. Avalonians are naturally born right-handed and thus the default is always to use that hand for wielding and striking with weapons.
DRAW To wield a weapon from your inventory or scabbard.
SHEATH To cease wielding a weapon and return it to scabbard.
WIELD RIGHT <weapon> Places the weapon specifically in your right hand.
SHOOT <target> To fire an arrow at a target; even from distance.
THROW <item> AT <foe> Hurls an item at a foe, potentially causing damage.
It is possible, as you develop further, to employ good use of weapons wielded in your left hand. Those with the specialist abilities can then pick and choose which hand to use for striking, or employ both together to strike a foe faster/more harmfully.
WIELD LEFT <weapon> Places the weapon specifically in your left hand.
STRIKE LEFT To select your left hand weapon to strike next.
STRIKE RIGHT To select your right hand weapon to strike next.
You can go to an Armoury and type HELP REPAIRS for information on how to repair a damaged weapon. Alternatively you could ask anyone with the Forging skill to come to your aid.
