Key ability: Charisma
Persuasion covers changing attitudes and influencing others through argument, negotiation, deception, or intimidation. It combines Bluff, Diplomacy, and Intimidate.
Persuasion checks normally use Charisma. Intimidating Presence allows Strength to replace Charisma on checks made to intimidate; it does not apply to other uses of Persuasion.
At 5 ranks, Persuasion grants a +2 Synergy bonus to Disguise checks to maintain a false identity through conversation.
