Cultist of Light

Devotion. The cultist has advantage on saving throws against being charmed or frightened.

Death Flash.  When the cultist dies, magical light flashes out from it in a 10-foot radius as its body and possessions, other than metal or magic objects, burn to ash. Any creature in that area must make a DC 11 Constitution saving throw. On a failure, the creature takes 3 (1d6) radiant damage and, if the creature can see the light, is blinded until the end of its next turn. If the saving throw is successful, the creature takes half the damage and isn’t blinded.

Multiattack. The cultist makes two melee attacks.

Dagger. Melee or Ranged Weapon Attack: +4 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 5 (1d4 + 2) piercing damage. If the cultist has advantage on the attack roll, the attack deals an extra 7 (2d6) piercing damage.
