Fantasy Politics - NPC Boons

NPCs can award more treasure than gold....
(Dragon Age: Inquisition)

Largely described in the Paizo Game Mastery Guide book, NPC boons are a non-treasure way of granting the characters some kind of benefit for helping an NPC with a little problem.  In a political quagmire of intrigue and eventfulness, these become all the more valuable.  While there are a variety of useful boons, the following are likely the most vital in a political situation, particularly when influential figures and wealthy recluses are avoiding or ignorant of the PCs cause.

1. Letter of Recommendation
2. Favourable Introduction
3. Invitation to an Event
4. Influences Another on Your Behalf
5. Teaches Local Etiquette
6. Describes Local Connections
7. Provides Blackmail Material
8. Assists in the Creation of a Scandal
9. Causes a Scene as a Distraction
10. Grants Minor, Landless Title
11. Discounts an Item for the Cause
12. Provides Appropriate Attire
13. Provides Entertainment at an Event
14. Functions as an Escort for VIP
