Influence (INF) represents a character's ability to inspire or manipulate others.
When in Quests, Influence can be rolled against in certain circumstances. Every two points of influence add 1 to their roll for either convincing someone or resisting being convinced.
When shopping, every point of Influence is a percentage reduction in cost during haggling.
All classes start with a certain amount of Influence. Leaders get the most.
Influence can be earned, at the DM's discretion.
