Amphibious. The dragon can breathe air and water.

Shadow Stealth. While in dim light or darkness, the dragon can take the Hide action as a bonus action.

Multiattack. The dragon makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 6) piercing damage.

Claw. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.

Breath Weapons (Recharge 5–6). The dragon uses one of the following breath weapons.

Chaos Breath. The dragon creates a shining bead of chaotic force in its mouth, then releases the energy in a 30-foot cone. Each creature in that area must make a DC 17 Strength saving throw. On a failed save, the creature takes 36 (8d8) force damage, and its speed becomes 0 until the start of the dragon’s next turn. On a successful save, the creature takes half as much damage, and its speed isn’t reduced.

Weakening Breath. The dragon exhales gas in a 30-foot cone. Each creature in that area must succeed on a DC 17 Strength saving throw or have disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws 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.

Slowing Breath. The dragon exhales gas in a 30-foot cone. Each creature in that area must succeed on a DC 17 Constitution saving throw. On a failed save, the creature can't use reactions, its speed is halved, and it can't make more than one attack on its turn. In addition, the creature can use either an action or a bonus action on its turn, but not both. These effects last for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a successful save.
