The rogue is an 'expert treasure hunter' living by his wits and often at others' expense. They are specialized in stealth, and cunning. Not only thieves fill the ranks of the rogue class: spies, scouts, detectives, pirates and many others are also rogues. They excel at detecting traps and prefer sneak attacks.
Seek a style that is shiny but dark. Chromes with black fit the bill, as also the sinister chrome in dark lettering styles.
