Bright Sorrow

Horrific Appearance. Any humanoid that starts its turn within 30 feet of the sorrow and can see the sorrow’s face must make a DC 11 Wisdom saving throw. On a failed save, the creature is frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if the sorrow is within line of sight, ending
the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the sorrow’s Horrific Appearance for the next 24 hours. Unless the target is surprised or the revelation of the sorrow’s true form is sudden, the target can avert its eyes and avoid making the initial saving throw. Until the start of its next turn, a creature that averts its eyes has disadvantage on attack rolls against the sorrow.

Luminous Body. The bright sorrow emits dim light in a 15-foot radius. As a bonus
action, the sorrow can increase the intensity of this light, turning it into bright light for 30 feet and dim light for an additional 30 feet. It can dim the light back to its normal state as a bonus action. While glowing, the sorrow has advantage on Charisma (Intimidation)
checks.
Truesight. The bright sorrow has truesight out to 60 feet, allowing it to see through illusions, invisibility, darkness, and even into the Ethereal Plane.

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10+3) slashing damage.
Radiant Pulse (Recharge 5–6). As an action, the bright sorrow can release a burst of searing light in a 15-foot radius. Each creature in the area must make a DC 13 Constitution saving throw, taking (10) 3d6 radiant damage on a failed save or half as much on a successful one. Creatures frightened by the sorrow automatically fail this saving throw.
