Diplomacy (Charisma)
You can influence others with your tact, subtlety,
and social grace. Make a Diplomacy check to change
opinions, to inspire good will, to haggle with a patron,
to demonstrate proper etiquette and decorum, or to
negotiate a deal in good faith.
A Diplomacy check is made against a DC set by the
DM. The target’s general attitude toward you (friendly
or unfriendly, peaceful or hostile) and other conditional
modifiers (such as what you might be seeking to
accomplish or what you’re asking for) might apply to
the DC. Diplomacy is usually used in a skill challenge
that requires a number of successes, but the DM might
call for a Diplomacy check in other situations.
