Charisma measures a character's force of personality, persuasiveness, personal magnetism, ability to lead, and physical attractiveness. This ability represents actual strength of personality, not merely how one is perceived by others in a social setting. Charisma is most important for paladins, favored souls, sorcerers, and bards. It is also important for clerics and blackguards, since it affects their ability to turn undead, and is important for spirit shamans and warlocks as it affect some of their spell DCs. Every creature has a Charisma score.

Charisma modifiers are applied to:

• Bluff, diplomacy, intimidate, perform, taunt and use magic device checks.
• Sorcerer, bard, spirit shaman, and warlock spell/invocation DCs
• Turning checks for clerics, paladins, and blackguards attempting to turn zombies, vampires, and other undead.
• All saving throws with Divine Grace, Dark Blessing and Dark One's Own Luck.

Sorcerers, bards, and favored souls get bonus spells based on their Charisma scores (see ability modifier). The minimum Charisma score needed to cast a sorcerer, bard, or favored soul spell is 10 + the spell's level.
