Persuasion

Attribute: Charisma
Persuasion, a skill at convincing other people to act as you wish them to, includes such things as haggling for a bargain, rousing a crowd to action, and convincing an enemy to let you go. The referee will set the difficulty level based upon the specific situation and exactly what sort of a speech you make.

This is only used to convince NPCs; all attempts to persuade other player characters
