Chameleon Skin. The troglo-wight has advantage on Dexterity (Stealth) checks made to hide.

Necrotic Stench. Any living creature that starts its turn within 5 feet of the troglo-wight must succeed on a DC 13 Constitution saving throw, or take 5 (2d4) necrotic damage and be poisoned until the start of the creature's next turn. On a successful saving throw, the creature cannot be poisoned by the stench of all troglodytes and troglo-wight for 1 hour. The creature can still take necrotic damage from a troglo-wight's necrotic stench during this hour, but only takes 2 (1d4) necrotic damage if they fail their saving throw.​

Sunlight Sensitivity. While in sunlight, the troglo-wight has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Multiattack. The troglo-wight makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 7 (1d8 + 3) piercing damage plus 5 (1d10) necrotic damage; if the target is a creature, it must succeed on a DC 13 Constitution saving throw or suffer 1 level of exhaustion. This exhaustion remains until it is healed magically: a Lesser Restoration can remove one level of exhaustion from a victim with two or fewer levels, a Greater Restoration will remove three levels of exhaustion. The target dies if it suffers 6 levels or exhaustion.​

 A humanoid slain by this attack rises 24 hours later as a zombie under the troglo-wight's control, unless the humanoid is restored to life or its body is destroyed. The troglo-wight can have no more than twelve zombies under its control at one time.

Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage plus 5 (1d10) necrotic damage.
