Banishing Light

You hold up your holy symbol and divine light radiates out from your symbol. Every creature of your choice within 15 ft radius sphere of you must make a Constitution saving throw. On a failed throw a creature takes 3d8 radiant damage or half as much on a successful throw. If the creature is undead or fiend it takes an additional 1d8 damage.

At Higher Level. Wen you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot above 2nd level.
