Thief
Official Information
Thieves are specialists in stealth and cunning, living by their wits more than by their strength. They shun metallic armor and shields because the weight limits their movement and dexterity. Weapons that pierce, like daggers, are their favorites.
An aarakocra, an elf, a gnome, a sahuagin, a half-elf, a halfling, or a human can be a Thief.

Thieves are not as powerful at dealing out damage as warrior or rangers, but they have many, many tricks up their sleeves. In addition to their abilities to sneak and hide, they are also able to steal from both mobs and other players, to pick locks, to use cant (a special thief language), and to listen in on conversations all over the world. Like rangers, thieves rely on their high dexterity to deftly move out of the way of attacks, rather than use metal armor. Too, when thieves initiate an attack they can often use a backstab, which is an attack that grows more and more devastating the bigger the thief becomes. Backstabbing can only be done with piercing weapons.
Thieves have the added benefit of learning how to use scrolls around level 11.
The primary stat for thieves is dexterity.
