Starry Score

This scroll is made from soft white vellum. When unrolled, it reveals dense silver writing in an unknown language. The starry score is a portion of a great opera performed by the eladrin to please their mistress, the Queen of Stars. A good-aligned bard who spends a use of bardic music can discern the words and notes recorded and perform them as a full-round action by making a Perform check. All evil outsiders who can clearly hear the bard perform and are within 30 feet must succeed on Will saves (DC equals the bard's perform check result) or be physically pained, taking a -5 penalty on attack rolls, damage rolls, saving throws, and checks. Conversely, all good outsiders gain a +5 sacred bonus on attack rolls, damage rolls, saving throws, and checks. Both effects last for as long as you continue to perform and for 3 rounds thereafter.
