Blade of Radiance

A blade of blinding light flies forth in a direction you choose, cutting a line 60 feet long and 5 feet wide. Each creature within the line must make a Wisdom saving throw, taking 8d6
radiant damage on a failed save, or half as much damage on a successful one. Infernals and undead have disadvantage on this saving throw.
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 level above 3rd.
