Equipment
From Guild Wars Wiki
Equipment pertains to items that are held by the character and used in combat, both in offense and defense. They are of two main kinds, armor and weapons.
[edit] Equipment slots
Each character has a total of seven equipment slots: Main hand and offhand for weapons and shields and five armor slots (head, chest, hands, legs and feet). Single handed weapons can only be equipped in the main hand and shields only in the offhand. There is no dual weapon wielding (or dual shield wielding) in Guild Wars.
[edit] Changing equipment
Equipment can be changed in all outposts and at any time during PvE. It is not possible to change your armour during PvP encounters, but you can change your weapon and off-hand.
[edit] Customized equipment
Equipment can be customized for a 20% damage enhancement by bringing a weapon to a weaponsmith. However customized weapons can only be used by the character they are customized for, or that character's heroes. Some equipment is automatically customized (for example armor and some weapons obtained from collectors, or armor from armorers).
