Divine Wave

You swing the weapon you use as the material component for this spell, and cause a wave of divine power to wash out from you in a direction of your choice.

Each creature in a 30 ft. cone must make a Dexterity saving throw. On a failure, a creature takes 6d6 radiant damage, or half as much on a success. If a creature is an Undead or a Fiend, it takes an extra 1d6 radiant damage from this spell.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 per level of spell slot above 4th.
