Vile Scar

+1 Shield. Requires attunement. You can activate the shield as a bonus action. Each creature you choose within 30 feet of you and that can see you must make a DC 15 Wisdom saving throw. On a failed saving throw, that creature is frightened for 1 minute, and continues to make saving throws to stop the effect at the end of their turn. You may use Frighten once and regain this use at dawn.
