Dazzling Laser

A magnificent ray of sparkling light shoots forth from you in a line that is 100 feet long, and reaches 5 feet across. Each creature within the line must make a Wisdom save, on a failed save the target takes 6d8 radiant damage and is stunned until the end of your next turn, on a successful save the target takes half damage and is not stunned.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
