Unresistible Grace

The duration lasts until the end of your performance. While the spell is active, you have +2 on all Charisma (CHA) rolls. It makes your voice sound nicer, your instruments play better, etc. Once the spell is finished you will have to make a CHA check of 15 to make the subjects think that nothing has changed. If you fail this check then the subjects may become awaret hat you used magic to influence your performance.
