You summon a massive hammer of holy light over your head, which then slams down and creates a fissure of holy light. All creatures in a line 30 feet long and 5 feet wide in a direction of your choice must make a Dexterity saving throw. A target takes 5d8 radiant damage on a failed save, or half as much damage on a successful one. A creature takes an additional 1d8 damage if it is undead or a fiend.

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

Classes : Paladin, Priest
