Offense
Bite
Circumstance: Melee
14 to hit, reach 5 ft., one target. (2d10 + 8) piercing damage plus 7 (2d6) poison damage, and the target must make a 19 Constitution saving throw. On a failed save, the target contracts Stygian Wasting.
Offense
Tail
Circumstance: Melee
14 to hit, reach 10 ft., one target. (2d6 + 8) bludgeoning damage. If the target is a Large or smaller creature, it has the grappled condition (escape 22). The dragon can't make a Tail attack while a creature is grappled in this way.
Action
Multiattack
The dragon can use its Frightful Presence. It then makes three attacks using its Bite, Tail, or a combination of the two. It can replace one of the attacks with Constrict.
Action
Constrict
The dragon tightens its grip on a creature grappled by its tail. The creature takes 27 (3d12 + 8) bludgeoning damage, has the restrained condition until the start of the dragon's next turn, and must make a 19 Constitution saving throw. On a failed save, the target contracts Stygian Wasting.
Action
Frightful Presence
Each creature of the dragon's choice that is within 120 feet of the dragon must succeed on a 18 Wisdom saving throw or have the frightened condition for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.
Action
Stygian Breath {@recharge 5}
The dragon exhales poisonous Styx water in a 60-foot-long, 10-foot-wide line. Each creature in that line must make a 19 Dexterity saving throw, taking 54 (12d8) poison damage on a failed save, or half as much on a successful one. Creatures that fail the save contract Stygian Wasting.
Legendary Action
Detect
The dragon makes a Wisdom (Perception) check.
Legendary Action
Tail Attack
The dragon makes a Tail attack. If a creature is already grappled, the dragon may use Constrict instead.
Legendary Action
Death Throw (Costs 3 Actions)
If the dragon has successfully restrained a creature with the Constrict ability, it may throw them up to 100 feet away. When it lands, the creature takes 21 (6d6) bludgeoning damage and must make a 18 Constitution saving throw. On a failed save, the creature has the unconscious condition for 10 minutes.
Trait
Amphibious
The dragon can breathe air and water.

Infernal
One of the only draconic beings that makes its home in the Nine Hells, the Styx dragon is an aquatic creature that lives within the River Styx. The waters of the Styx have no effect on its mental faculties or memories, and their breath weapon replicates the effects of the Styx. Their diet consists mostly of devils foolish enough to wander close to the banks of the Styx, though they prefer mortals and corpses over Fiends. Occasional Styx dragons have been spotted in non-infernal planes, possibly by traveling the Styx to their destination.
Unusual Dragons
Unlike other Dragons, the scales of the Styx dragon have no effect on their capabilities, and range from darker hues all the way up to chromatic scales, though they always appear muddied. They have no wings and very small limbs, relying primarily on their tails for mobility and combat. Their serpentine body lends itself to muddy nests along the banks of the Styx and quick underwater travel. Good captains know where Styx dragon clutches are along the river, and steer their boats specifically to avoid the creatures.
