Adult wind Dragon

• Innate Spellcasting. The dragon’s innate spellcasting ability is Charisma (spell save DC 18). It can innately cast the following spells, requiring no material components:
• At will: Feather fall
• 3/day: lightning bolt, ice storm
• Fog Vision. The dragon sees normally through light or heavy obscurement caused by fog, mist, clouds, or high wind.
• Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.
• Magic Resistance. The dragon has advantage on saving throws against spells and other magical effects.
• Uncontrollable. The dragon’s movement is never impeded by difficult terrain, and its speed can’t be reduced by spells or magical effects. It can’t be restrained (per the condition), and it escapes automatically from any nonmagical restraints (such as chains, entanglement, or grappling) by spending 5 feet of movement. Being underwater imposes no penalty on its movement or attacks.
• Whirling Winds. Gale-force winds rage around the dragon. Ranged weapon attacks against it are made with disadvantage.
• Uncontrollable. The dragon’s movement is never impeded by difficult terrain, and its speed can’t be reduced by spells or magical effects. It can’t be restrained (per the condition), and it escapes automatically from any nonmagical restraints (such as chains, entanglement, or grappling) by spending 5 feet of movement. Being underwater imposes no penalty on its movement or attacks.

• Multiattack. The wind dragon can use its Frightful Presence and then makes three attacks: one with its bite, and two with its claws.
• Bite. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 7) piercing damage.
• Claw. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.
• Tail. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 16 (2d8 + 7) bludgeoning damage.
• Breath of Gales (Recharge 5-6). The dragon exhales a blast of wind in a 60-foot cone. Each creature in that cone takes 27 (5d10) slashing damage and is pushed 25 feet away from the dragon and knocked prone; a successful DC 20 Strength saving throw halves the damage and prevents being pushed (but not being knocked Prone). All flames in the cone are extinguished.
• 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 repeats the saving throw at the end of its turn, 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.

Change Shape. The dragon magically transforms into any creature that is Medium or Small, while retaining its game statistics (other than its size). This transformation ends if the dragon is reduced to 0 hit points or uses a bonus action to end it.

Wind Step. The dragon magically teleports to an unoccupied space it can see within 60 feet of it.

The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action soption 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 10 feet of the dragon must succeed on a DC 21 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.
