Molten Spit

The dragon targets one creature within 60 feet forcing it to make a DC 25 Dexterity saving throw. The creature takes 27 (5d10) fire damage on a failure or half on a success. Liquid gold pools in a 5-foot-square occupied by the creature and remains hot for 1 minute. A creature that ends its turn in the gold or enters it for the first time on a turn takes 22 (4d10) fire damage.

Breath Weapons (Recharge 5-6)

The dragon uses one of the following breath weapons:

Molten Breath

The dragon exhales molten gold in a 90-foot cone. Each creature in the area makes a DC 25 Dexterity saving throw taking 88 (16d10) fire damage on a failed save or half damage on a success. A creature that fails the saving throw is covered in a shell of rapidly cooling gold reducing its Speed to 0. A creature can use an action to break the shell ending the effect.

Weakening Breath

The dragon exhales weakening gas in a 90-foot cone. Each creature in the area must succeed on a DC 25 Constitution saving throw or suffer disadvantage on weapon attack rolls for 1 minute. A weakened creature repeats the saving throw at the end of each of its turns ending the effect on a success.

Change Shape

The dragon magically takes the shape of a humanoid or beast or changes back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed or borne by the new form (dragons choice). In the new form the dragons stats are unchanged except for its size. It can't use Molten Spit Breath Weapons Tail Attack or Wing Attack except in dragon form. In beast form it can attack only with its bite and claws if appropriate to its form. If the beast form is Large or smaller the reach of these attacks is reduced to 5 feet. In humanoid form it can attack only with its greatsword.
