Influence (INF) represents a character's ability to inspire or manipulate others.
When in Quests, Influence can be rolled against in certain circumstances.
When shopping, every point of Influence is a percentage reduction in cost, against biological shopkeepers. For example, a character with 8 influence would only pay 92% of the price with a Skarg shopkeeper.
All classes start with a certain amount of Influence. Leaders get the most.
Influence can be earned, at the DM's discretion.
