The dragon roars at up to two creatures of its choice within 120 feet of it. Each target must succeed on a DC 17 CHA save or be vulnerable to lightning damage until the end of its next turn. A target resistant to lightning damage isn't resistant to it for the duration. A target immune to lightning damage is still immune to it, even if the target fails the save.

Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 17 WIS save or be frightened for 1 minute. A creature can repeat the save at the end of each of its turns, ending the effect on itself on a success. If a creature's save is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.

Lightning Breath

The dragon exhales lightning in a 90-foot line that is 5 feet wide. Each creature in that line must make a DC 19 DEX save, taking 60 (11d10) lightning damage on a failed save, or half as much damage on a successful one.

Multiattack

The dragon uses its Frightful Presence. It then makes one Bite attack and two Claw attacks. It can replace its Bite attack with a use of Repulsion Breath, if available.

Repulsion Breath

Recharge 6

The dragon exhales repulsion energy in a 60-foot cone. Each creature in that area must succeed on a DC 19 STR save or be pushed up to 30 feet away from the dragon.

Bonus Actions

Change Shape

The dragon magically transforms into a Beast or Humanoid that has a challenge rating no higher than its own, or back into its true form, which is Dragon. Any equipment it is wearing or carrying transforms with it or is borne by the new form (the dragon's choice). It reverts to its true form if it dies. In a new form, the dragon retains its Legendary Resistance trait and its HP, ability to speak, proficiencies, and INT, WIS, and CHA scores, as well as this bonus action.

GM Tips: Using Adult Bronze Dragon

3 tips available

When using Adult Bronze Dragon in your D&D 5e campaign, consider these tactical approaches:

Flight Control Strategy: Target flying creatures with spells like 'Hold Person', 'Web', or 'Grease' to ground them. Without flight restriction, they can escape melee range easily. Consider area denial spells below their flight altitude to force them into disadvantageous positions.
Aquatic Combat: This creature can swim at 40 ft. It has advantage in water environments. Consider fighting on land or using water-based spells against it.
Lightning Damage Awareness: Lightning attacks often have long range and high speed. Advise players to use cover and avoid metal armor/weapons. Water surfaces amplify lightning damage - avoid fighting near water.
