Mist-Bound Soul.
The Mistborn Thrall cannot be turned. If reduced to 0 hit points, it dissolves into fog unless it is on consecrated ground or within sunlight. In 1 minute, it reforms with half its HP unless consecrated.

Fog Cloak.
While in dim light or fog, the Mistborn Thrall has advantage on Dexterity (Stealth) checks and lightly obscures a 10-ft. radius area around it.

Whispers of the Lost.
Any creature that starts its turn within 10 feet of the Thrall must succeed on a DC 13 Wisdom saving throw or hear maddening whispers, granting disadvantage on their next attack roll or ability check before the end of their turn.

Multiattack.
The Mistborn Thrall makes two melee attacks.

Claw (Mist-Bitten). Melee Weapon Attack: +4 to hit, reach 5 ft., one target.
Hit: 7 (2d4 + 2) slashing damage. If the target is a creature, it must succeed on a DC 13 Constitution saving throw or gain 1 level of Fracture (see Fracture mechanics). This can only happen once per creature per day.

Fog Lure (Recharge 5–6).
The Thrall exhales mist in a 15-foot cone. Creatures in that area must succeed on a DC 13 Wisdom saving throw or be charmed for 1 minute, hearing whispers that sound like loved ones or past regrets. They may repeat the save at the end of each of their turns. While charmed, they move 10 feet toward the Thrall on their turn.
