Orthon

Unseen and All-Seeing. Orthons are infamous for their sharp senses. Because an orthon can become invisible at will, its quarry is often unaware of being hunted until the orthon strikes. The orthon's invisibility can be disrupted when the devil is attacked, however, so a strong counterattack is often the best defense against it.
A Sporting Chance. Orthons value the challenge of the chase and the thrill of one-on-one combat above all else. An orthon's first loyalty is to its archduke, but if it has no immediate assignment, an orthon might work for anyone who offers it the promise of a worthy struggle against a lethal foe. Because they travel widely, orthons are unequaled as guides through the layers of the Abyss.

Magic Resistance. The orthon has advantage on saving throws against spells and other magical effects.

Actions

Infernal Dagger. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 11 (2d4 + 6) slashing damage, and the target must make a DC 17 Constitution saving throw, taking 22 (4d10) poison damage on a failed save, or half as much damage on a successful one. On a failure, the target is also poisoned for 1 minute. The poisoned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Brass Crossbow. Ranged Weapon Attack: +7 to hit, range 100/400 ft., one target. Hit: 14 (2d10 + 3) piercing damage, plus one of the following effects:
1. Acid. The target must make a DC 17 Constitution saving throw, taking an additional 17 (5d6) acid damage on a failed save, or half as much damage on a successful one.
2. Blindness (1/Day). The target takes 5 (1d10) radiant damage. In addition, the target and all other creatures within 20 feet of it must each make a successful DC 17 Dexterity saving throw or be blinded until the end of the orthon's next turn.
3. Concussion. The target and each creature within 20 feet of it must make a DC 17 Constitution saving throw, taking 13 (2d12) thunder damage on a failed save, or half as much damage on a successful one.
4. Entanglement. The target must make a successful DC 17 Dexterity saving throw or be restrained for 1 hour by strands of sticky webbing. A restrained creature can escape by using an action to make a successful DC 17 Dexterity or Strength check. Any creature other than an orthon that touches the restrained creature must make a successful DC 17 Dexterity saving throw or become similarly restrained.
S. Paralysis (1/Day). The target takes 22 (4d10) lightning damage and must make a successful DC 17 Constitution saving throw or be paralyzed for l minute. The paralyzed target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
6. Tracking. For the next 24 hours, the orthon knows the direction and distance to the target, as long as it's on the same plane of existence. If the target is on a different plane, the orthon knows which one, but not the exact location there.

Reactions

Explosive Retribution. When it is reduced to 15 hit points or fewer, the orthon causes itself to explode. All other creatures within 30 feet of it must each make a DC 17 Dexterity saving throw, taking 9 (2d8) fire damage plus 9 (2d8) thunder damage on a failed save, or half as much damage on a successful one. This explosion destroys the orthon, its infernal dagger, and its brass crossbow.
