The jyoti breathes out a gout of radiant light in either a 60-foot line (5 feet wide) or in a 30-foot-long cone. Creatures in the area must make a DC 17 Dexterity saving throw or take 38 (11d6) radiant damage, or half as much on a successful save. Living creatures failing their Dexterity saving throw must succeed on a DC 17 Constitution saving throw or be blinded until the end of their next turn. Undead failing their Dexterity saving throw take an additional 11 radiant damage.
