Mesmer Equipment: Mesmers wear light armor and like most professions in Guild Wars 2, can swap between two unique weapon sets in combat once they reach level 7. Weapon sets can be swapped at any time by pressing the [`] key. In their main hand Mesmers can use a scepter or sword, while in their off-hand they can equip a focus, pistol, sword, or torch. Additionally, Mesmers can equip two-handed weapons including a greatsword and a staff.
