Amphibious. The mist dragon can breathe both water and air.

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: +12 to hit, reach 20 ft., one target. Hit: 18 (2d10 + 7) piercing damage plus 10 (3d6) fire damage.

Claw. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 17 (3d6 + 7) slashing damage.

Tail. Melee Weapon Attack: +12 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 18 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 or the effect ends for it, the creature is immune to the dragon’s Frightful Presence for the next 24 hours.

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

1. Obscuring Mist. The dragon exhales a murky opaque mist in a 60-foot cube that spreads around corners. This mist heavily obscures the area and remains for 1 minute, or until dispersed with a moderate or stronger wind (at least 10 miles per hour).

2. Scalding Mist. The dragon exhales a fiery blast of lingering mist in a 60-foot cone that spreads around corners. The mist lightly obscures the area and remains for 1 minute, or until dispersed with a moderate or stronger wind (at least 10 miles per hour). Each creature that enters the area or begins its turn there must make a DC 20 Constitution saving throw, taking 63 (18d6) fire damage on a failed saving throw, or half as much damage on a successful one. Being underwater doesn’t grant resistance to this damage.

Mist Form. The mist dragon polymorphs into a Huge cloud of mist, or back into its true form. While in mist form, the dragon can’t take any actions, speak, or manipulate objects. It is weightless, has a flying speed of 20 feet, can hover, and can enter a hostile creature’s space and stop there. In addition, if air can pass through a space, the mist can do so without squeezing, and it can’t pass through water. It has advantage on Strength, Dexterity, and Constitution saving throws, it is immune to all nonmagical 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 20 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.
