Adult White Dragon

The dragons movement and vision is not hindered by cold, icy surfaces, snow, wind, or storms. Additionally, the dragon can choose to burrow through snow and ice without leaving a trace.

The dragons spellcasting ability is Charisma (save DC 15). It can innately cast the following spells, requiring no material components.
- 3/Day Each: Dominate Beast, Fire Shield, Animal Friendship, Sleet Storm

When the dragon fails a saving throw, it can choose to succeed instead. When it does, it sheds some of its scales, which turn to ice. If it has no more uses of this ability, its Armor Class is reduced to 16 until it finishes a long rest.

Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) slashing damage.

The dragon exhales a 60-foot cone of frost. Each creature in the area makes a DC 19 Constitution saving throw. On a failure it takes 52 (15d6) cold damage and its speed is reduced to 0 until the end of its next turn. On a success it takes half damage.

The dragon attacks once with its bite and twice with its claws. In place of its bite attack it can spit ice.

The dragon targets a creature within 60 feet forcing it to make a DC 19 Dexterity saving throw. On a failure the target takes 16 (3d10) cold damage and its speed is reduced to 0 until the end of its next turn. On a success it takes half damage.

Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage and the dragon pushes the target 10 feet away.

When a creature the dragon can see within 10 feet hits the dragon with a melee attack, the dragon makes a tail attack against it.

For 1 minute, gusts of sleet emanate from the dragon in a 40-foot-radius sphere, spreading around corners. The area is lightly obscured and the ground is difficult terrain The first time a creature moves on its turn while in the area, it must succeed on a DC 15 Dexterity saving throw or fall prone (or fall if it is flying).

Each creature of the dragons choice within 120 feet that can hear it makes a DC 15 Charisma saving throw. On a failure, it is frightened for 1 minute. A creature repeats the saving throw at the end of its turn, ending the effect on itself on a success. When it succeeds on a saving throw or the effect ends for it, it is immune to Roar for 24 hours.

Only one legendary action can be used at a time and only at the end of another creatures turn. It regains spent legendary actions at the start of its turn.

The dragon beats its wings. Each creature within 15 feet makes a DC 19 Dexterity saving throw. On a failure, it is pushed 10 feet away and knocked prone. The dragon can then fly up to half its fly speed.
