Aurora's Aural Aura

You exert loudening magic in a 30-foot aura centered on yourself. Within this area, creatures cannot become hidden from one another or benefit from invisibility, as their movements become obtrusively loud. A creature that is under the effects of a silence spell or similar magic is immune to this effect. Whenever a creature takes thunder damage while within this area, the damage dealt is increased by a number equal to your spellcasting modifier and the creature is deafened until the end of their next turn.
