Cero

A beam of brilliant light flashes out from your hand in a 5-foot-wide, 120-foot-long line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 3d8 fire damage and 2d6 thunder damage and is blinded until your next turn. On a successful save, it takes half as much damage and isn't blinded by this spell. Undead and oozes have disadvantage on this saving throw.
