Rogues have little in common with one another. Some are stealthy thieves. Some are silver-tongued tricksters. Still others are scouts, infiltrators, spies, diplomats, or thugs. What they do share is versatility, adaptability, and resourcefulness. In general, rogues are skilled at getting what others don't want them to get: entrance into a locked treasure vault, safe passage past a deadly trap, secret battle plans, or a guard's trust.
The rogue's stealth and trap-finding ability make her an amazing scout.
All simple weapons (plus rapier, short sword and shortbow), light armor, and no shields.
