Blue Rays

When you cast the spell, and as an action on each of your turns until the spell ends, you can create a 60 foot line of shimmering blue energy. Each creature on the line must make a Dexterity saving throw, taking 3d6 lightning and 3d6 radiant damage on a failure or half as much on a success.

At Higher Levels. When you cast this spell with a spell slot of 6th level or higher, you can increase the lightning or the radiant damage (but not both) by 1d6 for each level above 5th.
