Dragons fear

Beginning at 18th level, you can channel the dread presence of your dragon ancestor, causing those around you to become frightened. As an action, you can spend 5 sorcery points to draw on this power and exude an aura of fear (your choice) to a distance of 60 feet. For 1 minute or until you lose your concentration (as if you were casting a concentration spell), each hostile creature that starts its turn in this aura must succeed on a Wisdom saving throw or be frightened until the aura ends. A creature that succeeds on this saving throw is immune to your aura for 24 hours.
