Thievery

Thievery is the set of skills that let you take what isn't yours and avoid capture before and after doing so. The Rogue class offers plenty of bonuses here, but every class can benefit from a little extra subtlety.
 * Burglary includes skills necessary when someone puts measures to keep their things safe that you want. Some skills require certain tools while others just require you to not be noticed, depending on what you're stealing and how you're trying to do it.
 * Espionage involves finding information others put effort into not being found, plus the art of changing information you want to change.
 * Stealth involves the sneaking mechanic and offers skills associated with having an easier time not being found and combat bonuses from attacking while sneaking.
