Diplomacy
IQ/Hard
Defaults: IQ-6 or Politics-6.
This is the skill of negotiating, compromising, and getting along with others. You may substitute a Diplomacy roll for any reaction roll in a noncombat situation, as described under Influence Rolls (p. 359).
Unlike other Influence skills, Diplomacy never gives a worse result than if you had tried an ordinary reaction roll. Failure with Fast-Talk or Sex Appeal alienates the subject, but Diplomacy is usually safe.
If you know Diplomacy at level 20 or better, you get a +2 bonus on all reaction rolls!
A successful roll also allows you to predict the possible outcome of a course of action when you are negotiating, or to choose the best approach to take.
