Energy Blast

A wave of destructive arcane energy blasts forth from your outstretched hands. A creature caught in the 20-foot cone must make a Dexterity saving throw. A creature takes 6d6 force damage on a failed save or, half as much damage on a successful one. If you've taken damage from a spell attack in the last round, the spell does an additional 2d6 lightning damage and a creature who fails their save is stunned until the end of their next turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot above 3rd, and the additional damage increases by 1d6 for every three slots above 3rd.
