Xanathar's Guide to Everything
0-level (Cantrip) Evocation
You utter a divine word, and burning radiance erupts from you. Each creature of your choice that you can see within range must succeed on a Constitution saving throw or take 1d6 radiant damage.
The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
