Candle Jack

Namebound Curse.  If a creature says "Candle Jack" aloud within 60 feet of him or an object he's enchanted (e.g. a children's rhyme, a puppet, or candle), the creature must succeed on a DC 13 Charisma saving throw or become Marked for 8 hours.  Candle Jack can sense the direction of Marked creatures within 1 mile and has advantage on attack rolls against them.  

Shadowstep. Once per turn, Candle Jack can teleport up to 30 feet to a space he can see in dim light or darkness.

Multiattack. Candle Jack makes two Binding Cord attacks

Binding cord.  Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 8(1d8 + 4) slashing damage.  Target must succeed on a DC 13 Strength saving throw or be Restrained until the end of its next turn.  

Name Reaper (1/day). Candle Jack targets up to two creatures within 30 feet who have spoken his name in the last 24 hours.  They must each make a DC 14 Constitution saving throw.   On a failed save, they take  18 (4d8) necrotic damage.  On a successful save, they take half damage.  

Snuff the Light. He extinguishes a mundane light source (torch, candle, lantern) within 30 feet. Magical light requires a DC 13 spellcasting ability check to resist snuffing.  

Fear the Sack (Thematic/Utility Only).  When a creature drops to 0 HP, Candle Jack may use his reaction to whisk their unconscious body into his Burlap Sack. The creature is considered stable but unconscious.  The sack can hold only 1 creature.  The creature remains trapped until freed (DC 15 Strength check from outside, or dispel magic on the sack).  If Jack is reduced to 0 HP, the sack ruptures.
