Dragon's Roar

Powerful magical energetic waves emerge from your hands and empower your voice, allowing your speech to mutate so that you have a dragon's voice. This allows you to let out a dragon's dreadful roar. For the spell's duration, you can use a bonus action to let out a terrible and frightening roar that strikes fear into the hearts of all creatures within 60ft. Each target within that range has to succeed on a Wisdom save or take 3d6 psychic in addition to being frightened of you (the save can't be repeated). On a success, a target takes half damage and no other effect.

Also, you can use the energy of pure fright in the target experiences to improve your abilities. For each creature that fails the save, you get a +1 bonus to ability checks, saves, or attack rolls up to a max of 5. If more than 1 target fails, you can split it among the different rolls. For example, if 3 targets fail, you can give yourself a +3 bonus on attacks or a +1 bonus on attacks, ability checks or saves.
