Dragon's Roar

Unleash a bellowing, ear-jarring roar in a 30 ft. directional cone.  Each creature in the line must make a Wisdom saving throw.  A creature takes 1d12 force damage and is stunned for the duration on a failed save, or half as much and is not stunned on a successful save.  The target(s) may repeat the saving throw at the end of their turn, ending the effect on a success.  

At Higher Levels. When you cast this spell at 4th level, or higher, the damage increases by 1d12 for every spell slot above 3rd.  At 4th level, or higher, the range increases by 5ft. for every spell slot above 3rd.
