Templar's Wrath

You lash out at all nearby creatures with divine power. Each creature within 15 feet of you must make a Constitution saving throw. On a failure, an affected creature takes 8d6 Radiant damage and is frightened of you until the end of its next turn. On a success, it takes half damage and is not frightened.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, increase the damage by 2d6 per spell level.
