Beam of Radiance

A beam of fire blasts out of your mouth to a point you choose within range impacting your selected target in the chest. The targeted creature selected must make a Dexterity Saving Throw. The target take 5d8 radiant damage on a failed save, or half as much damage on a successful one.

It ignites flammable objects, but cannot go through walls.

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