Change Shape. The dragon magically polymorphs into a humanoid or beast that has a challenge rating no higher than its own, or 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 (the dragon's choice).
In a new form, the dragon retains its alignment, hit points, Hit Dice, ability to speak, proficiencies, Legendary Resistance, lair actions, and Intelligence, Wisdom, and Charisma scores, as well as this action. Its statistics and capabilities are otherwise replaced by those of the new form, except any class features or legendary actions of that form.

Lair: (Note only Adult and Ancient dragons get access to lair actions)
Copper dragons dwell in dry uplands and on hilltops, where they make their lairs in narrow caves. False walls in the lair hide secret antechambers where the dragon stores valuable ores, art objects, and other oddities it has collected over its lifetime. Worthless items are put on display in open caves to tantalize treasure seekers and distract them from where the real treasure is hidden.
On initiative count 20 (losing initiative ties), the dragon takes a lair action to cause one of the following effects:
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.
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.
Fizban's Treasury of Dragons introduced the following additional lair actions:
The dragon chooses a point on the ground that it can see within 120 feet of it. A cloud of pink gas fills a 20-foot-radius sphere centered on that point. Each creature in that area that fails a DC 15 Wisdom saving throw is Incapacitated with laughter until the end of its next turn.
The dragon chooses a creature it can see within 120 feet of it. If the target fails a DC 15 Constitution saving throw, its speed is halved, and it can't use reactions or bonus actions until the end of its next turn.
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.
Intelligent creatures within 1 mile of the dragon's lair are prone to fits of giggling. Even serious matters suddenly seem amusing.
Fizban's Treasury of Dragons added the additional Regional Effects:
The ethereal music of woodwinds and bells can be heard carried on the wind within 1 mile of the dragon's lair.
Standing stones are common on hilltops within 1 mile of the dragon's lair. The stones shed dim light in a 10-foot radius at night. (If the dragon dies, the stones remain, but they no longer shed light.)
Fizban's Treasury of Dragons gave Copper Dragons the ability to cast the following spells once a day with no material components:
Young: (Save DC13) lesser restoration phantasmal force
Adult: (Save DC16) lesser restoration phantasmal force stone shape
Ancient: (Save 19) lesser restoration move earth phantasmal force stone shape
