Actions

Multiattack. The dragon can use its Aura of Madness. It then makes three attacks: one with its bite and two with its claws.
Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 7) piercing damage plus 7 (2d6) cold damage.
Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage plus 3 (1d6) cold damage.
Tail. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 16 (2d8 + 7) bludgeoning damage.
Aura of Madness.

As ancient void dragon, with DC 18 Wisdom saving throw.
Breath Weapons (Recharge 5–6).

The dragon uses one of the following breath weapons:
Gravitic Breath.

The dragon exhales a 60-foot cube of powerful localized gravity, originating from the dragon. Falling damage in the area increases to 1d10 per 10 feet fallen. When a creature starts its turn within the area or enters it for the first time in a turn, including when the dragon creates the field, must make a DC 20 Dexterity saving throw. On a failure the creature is restrained. On a success the creature’s speed is halved as long as it remains in the field. A restrained creature repeats the saving throw at the end of its turn. The field persists until the dragon’s breath recharges, and it can’t use gravitic breath twice consecutively.
Stellar Flare Breath.

The dragon exhales star fire in a 60- foot cone. Each creature in that area must make a DC 20 Dexterity saving throw, taking 31 (9d6) fire damage and 31 (9d6) radiant damage on a failed save, or half as much damage on a successful one.
Teleport.

The dragon magically teleports to any open space within 100 feet.

Reactions

Void Twist. When the dragon is hit by a ranged attack it can create a small rift in space to increase its AC by 5 against that attack. If the attack misses because of this increase the dragon can choose a creature within 30 feet to become the new target for that attack. Use the original attack roll to determine if the attack hits the new target.

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.
Void Slip (Costs 2 Actions). The dragon twists the fabric of space. Each creature within 15 feet of the dragon must succeed on a DC 18 Dexterity saving throw or take 12 (2d6 + 5) bludgeoning damage and be knocked prone. The dragon can then teleport to an unoccupied space within 40 feet.
Void Cache (Costs 3 Actions). The dragon can magically reach into its treasure hoard and retrieve one item. If it is holding an item, it can use this ability to deposit the item into its hoard.
