Amphibious. The dragon can breathe air and water.








Breath Weapons (Recharge 5–6). The dragon uses one of the following breath weapons.



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.

Legendary Actions


Detect. The dragon makes a Wisdom (Perception) check.

Tail Attack. The dragon makes a tail attack.

Wing Attack (Costs 2 Actions). The dragon beats its wings. Each creature within 10 feet of the dragon must succeed on a DC 20 Dexterity saving throw or take 14 (2d6 + 7) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.

A Bronze Dragon’s Lair

A bronze dragon lairs in coastal caves. It might salvage a wrecked ship, reconstruct it within the confines of its lair, and use it as a treasure vault or nest for its eggs.

Lair Actions


  • The dragon creates fog as though it had cast the fog cloud spell. The fog lasts until initiative count 20 on the next round.
  • 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.

Regional Effects

The region containing a legendary bronze dragon’s lair is warped by the dragon’s magic.

  • 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.
  • 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.

If the dragon dies, changed weather reverts to normal, as described in the spell, and the other effects fade in 1d10 days.
