You Know a Guy
Let's face it; your little black book is something on the far side of ridiculous — you have friends in all sorts of places. Whenever the need arises (maybe the party needs some equipment, an inside scoop on someone, or a spy) you can make a Charm + Lore roll against a Difficulty determined by the GM. If successful, it means you know someone applicable to the situation that owes you a favor. Roll a d10. On a 1–4, the appropriate contact is very minor and unrelated really (a friend of a friend of a friend). On a 5–7, the contact is directly related to the situation, but is low on the proverbial ladder. On an 8–9, the contact holds moderate importance and power and on a 10, the contact is not only very reliable and valid, but also can get you more than you asked for. As in all matters, the GM is adjudicator and will define the nature of the contact.
This is a more masterful version of Contact.
