Azure dragon

This dragon is a kind loving to some and it is a rare creature taking millions of years to find just one in my d&d lore the first one was found living in a cave near the coast-drae black hand said it looked like a red dragon with azure scales and blue eyes but it was calm and talkative not like a red dragon and more buttiful than one too talking about nature and more.... 

Lair Actions

On initiative count 20 (losing initiative ties), the dragon takes a lair action to cause one of the following effects; the dragon can’t use the same effect two rounds in a row:

• Pools of water that the dragon can see within 120 feet of it surge outward in a grasping tide. Any creature on the ground within 20 feet of such a pool must succeed on a DC 15 Strength saving throw or be pulled up to 20 feet into the water and knocked prone.
• A cloud of fast moving water about in a 20-foot-radius sphere centered on a point the dragon can see within 120 feet of it. The cloud spreads around corners. Each creature in it must succeed on a DC 15 Constitution saving throw or be blinded 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.
• The dragon creates fog as though it had cast the fog cloud spell. The fog lasts until initiative count 20 on the next round.The dragon chooses a 10-foot-square area on the ground that it can see within 120 feet of it The ground in that area turns into 3-foot-deep mud. Each creature on the ground in that area when the mud appears must succeed on a DC 15 Dexterity saving throw or sink into the mud and become restrained. A creature can take an action to attempt a DC 15 Strength check, freeing itself or another creature within its reach and ending the restrained condition on a success. Moving 1 foot in the mud costs 2 feet of movement. On initiative count 20 on the next round, the mud hardens, and the Strength DC to work free increases to 20.
• A thunderclap originates at a point the dragon can see within 120 feet of it. Each creature within a 20-foot radius centered on that point must make a DC 15 Constitution saving throw or take 5 (1d10) thunder damage and be deafened until the end of its next turn.
• The dragon chooses a point on the ground that it can see within 120 feet of it. Stone spikes sprout from the ground in a 20-foot radius centered on that point. The effect is otherwise identical to the spike growth spell and lasts until the dragon uses this lair action again or until the dragon dies.
• One creature the dragon can see within 120 feet of it must succeed on a DC 15 Charisma saving throw or be banished to a dream plane, a different plane of existence the dragon has imagined into being. To escape, the creature must use its action to make a Charisma check contested by the dragon’s. If the creature wins, it escapes the dream plane. Otherwise, the effect ends on initiative count 20 on the next round. When the effect ends, the creature reappears in the space it left or in the nearest unoccupied space if that one is occupied.
• Grasping roots and vines erupt in a 20-foot radius centered on a point on the ground that the dragon can see within 120 feet of it. That area becomes difficult terrain, and each creature there must succeed on a DC 15 Strength saving throw or be restrained by the roots and vines. A creature can be freed if it or another creature takes an action to make a DC 15 Strength check and succeeds. The roots and vines wilt away when the dragon uses this lair action again or when the dragon dies.
• A wall of tangled brush bristling with thorns springs into existence on a solid surface within 120 feet of the dragon. The wall is up to 60 feet long, 10 feet high, and 5 feet thick, and it blocks line of sight. When the wall appears, each creature in its area must make a DC 15 Dexterity saving throw. A creature that fails the save takes 18 (4d8) piercing damage and is pushed 5 feet out of the wall’s space, appearing on whichever side of the wall it wants. A creature can move through the wall, albeit slowly and painfully. For every 1 foot a creature travels through the wall, it must spend 4 feet of movement. Furthermore, a creature in the wall’s space must make a DC 15 Dexterity saving throw once each round it’s in contact with the wall, taking 18 (4d8) piercing damage on a failed save, or half as much damage on a successful one. Each 10-foot section of wall has AC 5, 15 hit points, vulnerability to fire damage, resistance to bludgeoning and piercing damage, and immunity to psychic damage. The wall sinks back into the ground when the dragon uses this lair action again or when the dragon dies.

Regional Effects

The region containing a legendary azure dragon’s lair is warped by the dragon’s magic, which creates one or more of the following effects:

• Tracks appear in the snow ect. within 6 miles of the dragon’s lair. The tracks lead to safe shelters and hidden water sources, while also leading away from areas that the dragon prefers to remain undisturbed.
• A blisteringly cold wind blows through the lair near the dragon. Each creature within 120 feet of the dragon must succeed on a DC 15 Constitution saving throw or take 5 (1d10) cold damage. Gases and vapors are dispersed by the wind, and unprotected flames are extinguished. Protected flames, such as lanterns, have a 50 percent chance of being extinguished.
• Vegetation grows faster such as vines trees and big plants 
• Chilly fog lightly obscures the land within 6 miles of the dragon’s lair.
• Whenever a creature with an Intelligence of 3 or higher comes within 30 feet of a water source within 1 mile of the dragon’s lair, the dragon becomes aware of the creature’s presence and location.
• Underwater plants within 6 miles of the dragon’s lair take on dazzlingly brilliant hues.
• Within its lair, the dragon can set illusory sounds, such as soft music and strange echoes, so that they can be heard in various parts of the lair.
• Magic carvings of the dragon’s smiling visage can be seen worked into stone terrain and objects within 6 miles of the dragon’s lair.
• Tiny beasts such as rodents and birds that are normally unable to speak gain the magical ability to speak and understand Draconic while within 1 mile of the dragon’s lair. These creatures speak well of the dragon, but can’t divulge its whereabouts.
• Once per day, the dragon can alter the weather in a 6-mile radius centered on its lair. The dragon doesn’t need to be outdoors; otherwise the effect is identical to the control weather spell.
• Whenever a creature that can understand a language sleeps or enters a state of trance or reverie within 6 miles of the dragon’s lair, the dragon can establish telepathic contact with that creature and converse with it in its dreams. The creature remembers its conversation with the dragon upon waking.
• Banks of beautiful, opalescent mist manifest within 6 miles of the dragon’s lair. The mist doesn’t obscure anything. It assumes haunting forms when evil creatures are near the dragon or other non-evil creatures in the mist, warning such creatures of the danger.
• Gems and pearls within 1 mile of the dragon’s lair sparkle and gleam, shedding dim light in a 5-foot radius.
• Rodents and birds within 1 mile of the dragon’s lair serve as the dragon’s eyes and ears. Deer and other large game are strangely more abundant 
• Given days or longer to work, the dragon can make clouds and fog within its lair as solid as stone, forming structures and other objects as it wishes.

If the dragon dies, vegetation remains as it has grown, but other effects fade over 1d10 days.
