Divine Light

You offer a prayer to a god or celestial being so they may strike down your foes. A beam of divine light crashes down on a point you choose within range 1d10 turns later, at the end of a creature's turn. Each creature in a 20-foot-radius, 100-foot-high cylinder centered on that point must make a Dexterity saving throw. A target takes 8d6 radiant damage on a failed save, or half as much damage on a successful one.

The light spreads around corners. It ignites flammable objects in the area that aren’t being worn or carried.

At Higher Levels
When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
