Qwyllion

Because of the qwyllion's nauseating nature, spellcasters have disadvantage on concentration checks while within 40 feet of the qwyllion.

The qwyllion is nauseatingly corrupt. Any creature that starts its turn within 20 feet of the qwyllion must succeed on a DC 14 Constitution saving throw or be poisoned for 1d8 rounds. If a creature that's already poisoned by this effect fails the saving throw again, it becomes incapacitated instead, and a creature already incapacitated by the qwyllion drops to 0 hit points if it fails the saving throw. A successful saving throw renders a creature immune to the effect for 24 hours. Creatures dominated by the qwyllion are immune to this effect.

The qwyllion uses its deadly gaze if it can, and makes two claw attacks.

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 24 (3d12 + 5) slashing damage.

The qwyllion turns its gaze against a single creature within 20 feet of the qwyllion. The target must succeed on a DC 14 Constitution saving throw or take 16 (3d8 + 3) necrotic damage and be incapacitated until the start of the qwyllion's next turn. A humanoid slain by a qwyllion's death gaze rises 2d4 hours later as a specter under the qwyllion's control.
