Decimation Bolts

You fire ten bolts of destructive elemental power. Each bolt fills a line 500ft long and 5ft wide. Each creature within the area must make a Dexterity save, taking 20d6 lightning damage and become stunned until the end of its next turn, taking half as much damage on a pass and isn't stunned.

Any spells or magical effects within the area of one or more bolts are dispelled.
