Burning Radiance

6th-level evocation (illumination)

Casting Time: 1 action
Range: Self (60-foot line)
Components: V, S
Duration: Instantaneous

A line of light 60 feet long and 5 feet wide emanates from you in a direction of your choice. Each creature in the line must make a Dexterity saving throw. On a failed save, a creature takes 10d8 radiant damage and catches fire; until someone takes an action to douse the fire, the creature takes 1d10 fire damage at the start of each of its turns. A successful saving throw halves the damage and prevents a creature from catching fire.

The burning radiance ignites flammable objects in the area that aren’t being worn or carried.
