Fearsome Dragon Mask

Prerequisite: The ability to invoke a dragon mask

You can manipulate the visage of your dragon mask to be a terrifying sight to your foes. Any target struck by your mask’s bite attack must make a successful Wisdom saving throw against your spell save DC or be frightened of you until the end of your next turn. If you augmented the attack with a spell slot, the frightened condition lasts an additional number of rounds = the level of the expended spell slot.
