Thief

Thief Class Overview

Waiting in the shadows, planning where they'll strike next, the mischievous Thieves are a force to reckon with. Swift and powerful, few can keep up with a Thief's attack speed and power, whether they're slashing their way in battle with a sharp dagger, or striking from afar with a bow. Striking them down isn't easy either, coupling their high flee with the ability to become invisible and poison their pursuers, Thieves have only magic to fear.

A Thief just wouldn't be a Thief if they weren't able to steal from their enemies, which makes them in turn quite adept at item gathering and money making. If the player decides to play as a Thief, frantic battles and high degrees of fun are guaranteed. They're also a very good choice as first characters, since in the beginning they don't have to rely as heavily on equipments to be able to fight consistently.
