Divine Cross

You brandish the weapon used in the spell’s casting infusing it with radiant energy. You then release the energy with a swing in a 30 feet long 5 feet wide line in front of you. The radiant energy also extends in a 15 foot line on each side from the 20 ft mark of the original line forming a cross. Each creature in the cross must make a Dexterity saving throw. A creature takes 3d8 radiant damage on a failed save, or half as much damage on a successful one. The damage increases by 1d8 if the target is an undead or a fiend.

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