Dungeons and Dragon Ball (Ver. O.1.2)

You form a singing sphere of power between your hands before unleashing it as a devastating beam. The beam travels in a line that is 5 feet wide and up to 150-feet long, moving in a direction of your choice and stopping early if it impacts an object or creature it can’t destroy. If the beam would strike a creature, it must make a Dexterity saving throw. On a failed save, they take 4d10 + 10 force damage. If they are reduced to 0 hit points by this effect, they are turned to ash and the beam passes through them. On a successful save, the beam passes by them and continues on. If an object or creature that is damaged by this spell is not reduced to 0 hit points, the line stops in their space and erupts into an earth-shaking blast. Every creature within 10-feet of the target must make a Dexterity saving throw, taking 4d6 force damage on a failed save or half as much on a success. When you cast using a spell of 6th level or higher, the damage of the initial effect increases by 1d10.
