You touch your ally, and her eyes mist over momentarily. You know she is seeing an image of her deity, imploring her to battle in his name.

You give the subject creature a brief vision of a divine entity that is giving it support and inspiring it to continue. The creature gets a morale bonus equal to your Charisma modifier on a single saving throw. It must choose to use the bonus before making the roll to which it applies. Using the bonus discharges the spell.
