Dragons Blessing

When you reach 17th level, you have been bonded so long with your drake and have learned more about its draconic powers that you can empower it to transform in to a dragon for a short while.

As a bonus action, it can let out a terrifying roar. Each creature of its choice that is within 120 feet of the drake and aware of it, must succeed on a Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to this effect for the next 24 hours.
