Fear Aura. A creature hostile to the pit fiend that starts its turn within 20 feet of it makes a DC 18 Wisdom saving throw . On a failure, it is frightened until the start of its next turn. On a success, it is immune to this pit fiend’s Fear Aura for 24 hours.

ACTIONS
Multiattack. The pit fiend attacks with its bite and mace.
Bite. Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 22 (4d6 + 8) piercing damage. If the target is a creature, it makes a DC 20 Constitution saving throw . On a failure, it is poisoned for 1 minute. While poisoned in this way, the target can’t regain hit points and takes 21 (6d6) ongoing poison damage at the start of each of its turns. The target can repeat this saving throw at the end of each of its turns, ending the effect on a success.
Mace. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 22 (4d6 + 8) bludgeoning damage plus 21 (6d6) fire damage. If the target is a Medium or smaller creature, it makes a DC 22 Strength saving throw On a failure, it is pushed 15 feet away from the pit fiend and knocked prone .
Circle of Fire (1/Day, While Bloodied). A 15-foot-tall, 1-foot-thick, 20-foot-diameter ring of fire appears around the pit fiend, with the pit fiend at the center. The fire is opaque to every creature except the pit fiend. When the ring of fire appears, each creature it intersects makes a DC 18 Dexterity saving throw , taking 22 (5d8) fire damage on a failed save or half damage on a successful one. A creature takes 22 (5d8) damage the first time each turn it enters the area or when it ends its turn there. The fire lasts 1 minute or until the pit fiend dismisses it, becomes incapacitated , or leaves its area.
Fireball (3rd-Level; V, S). Fire streaks from the pit fiend to a point within 120 feet and explodes in a 20-foot radius, spreading around corners. Each creature in the area makes a DC 18 Dexterity saving throw , taking 21 (6d6) fire damage on a failed save or half damage on a success.
Hold Monster (5th-Level; V, S, Concentration). A creature within 60 feet that the pit fiend can see makes a DC 18 Wisdom saving throw . On a failure, it is paralyzed for 1 minute. The creature repeats the save at the end of each of its turns, ending the effect on a success.
BONUS ACTIONS
Claw. Melee Weapon Attack: +14 to hit, reach 10 ft., one creature. Hit: 19 (2d10 + 8) slashing damage, and the target is grappled (escape DC 22). While the target is grappled, the pit fiend can’t use its claw against a different creature.
Tail. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 24 (3d10 + 8) bludgeoning damage.
Combat
The pit fiend prefers to bite opponents that haven’t yet been poisoned . If three or more enemies are gathered together, it may instead use Fireball .
For its bonus action, the pit fiend attacks with its tail unless it’s near a weak melee attacker, in which case it grapples with its claw.
When the pit fiend is bloodied, it flies to the nearest ranged attacker and uses Circle of Fire, which blocks line of sight for many enemies and prevents creatures from easily escaping it. While fighting in the circle, it uses its Mace attack to push opponents through the flames, forcing them to take even more damage if they run back through the flames to reach the pit fiend.

Legends and Lore
With an Arcana or Religion check, characters can learn the following:
DC 10 Many scholars believe that devils are angels that fell from grace. When touched by evil, mortal souls may transform into devils, as well.
DC 15 Neither fire nor poison harms a devil, and even magical darkness doesn’t impede a devil’s vision. They are supernaturally resistant to mundane damage, although magical and silvered weapons wound them normally.
DC 20 Though irredeemably evil, devils can be bargained with at the bargainer’s peril. They generally keep their word.
Pit fiends are the undisputed tyrants of hell, each subservient only to the archdevil that rules its plane. They command vast legions of devils and are generally considered to be among the most brilliant tacticians in the multiverse. If pit fiends have a weakness, it is pride: since only the most ambitious devils ever reach their lofty status, pit fiends believe their merit to be self-evident. Though it is not unknown for a pit fiend to face demotion after a crushing military defeat, more often it is a misstep navigating hell’s political landscape that leads to a pit fiend’s downfall.
