Special Traits

• Amphibious. The dragon can breathe air and water.
• Legendary Resistance (3/day). If the dragon fails a saving throw, it can choose to succeed instead.

Actions

• Multiattack. The dragon uses its Frightful Presence and makes three attacks: one with its bite and two with its claws.
• Bite. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 18 (2d10 + 7) piercing damage plus 5 (1d10) fire damage.
• Claw. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 14 (2d6 + 7) slashing damage.
• Tail. Melee Weapon Attack: +13 to hit, reach 20 ft., one target. Hit: 16 (2d8 + 7) bludgeoning damage.
• Frightful Presence. Each creature of the dragon’s choice that is within 120 feet of the dragon and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened 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 of the effect ends for it, the creature is immune to the dragon’s Frightful Presence for the next 24 hours.
• Steam Breath (Recharge 5-6). The dragon exhales steam in a 60 cone. Creatures in the area must make a DC 19 Constitution saving throw. On a failed saving throw, the creature takes 63 (18d6) fire damage, or half as much damage on a successful saving throw. Being underwater doesn’t grant resistance to this damage.

Legendary Actions

The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The dragon regains spent legendary actions at the start of its turn.

• Detect. The dragon makes a Wisdom (Perception) check.
• Tail Attack. The dragon makes a tail attack.
• Wing Attack (Costs 2 Actions). The dragon beats its wings. Each creature within 15 feet of the dragon must succeed on a DC 24 Dexterity saving throw or take 14 (2d6 + 7) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
