Anthem of Unraveling

 You unleash a powerful anthem of pure, resonant knowledge from Oghma's Yarting. Its sound physically dismantles that which resists understanding. Each creature in a 30-foot cone must make a Constitution saving throw. On a failed save, a creature takes 6d6 force damage and is pushed 10 feet away from you. On a successful save, a creature takes half as much damage and isn't pushed. Constructs and creatures heavily armored by magical means (such as those benefiting from Mage Armor or Plate Armor +1) have disadvantage on this saving throw.
