The Aristocrat is an interesting individual. They are very concerned about their social status and wealth. In fact, they are often invited to prestigious events and sometimes requested for unique or special quests. Their social status often helps their reaction when speaking with others as well.
Aristocrats have an estate, which is managed by themselves or a steward. This helps them receive regular income as others utilize the estate while the Aristrocrat is out adventuring. It also makes a nice place for the party to rest when returning from an adventure (no inn costs)!
While they aren't great warriors, they do have some training with combat (mostly because of dueling and practice). Because of this, they can be fairly good with a Rapier or Short Sword.
Finally, they have a knack for finding and recruiting extra talent and hirelings because of their reputation.
