Skills

Actions

• 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 Sleep Breath, if available.
• Bite. _Melee Weapon Attack:_ +14 to hit, reach 15 ft., one target. _Hit:_ 19 (2d10+8) piercing damage.
• Claw. _Melee Weapon Attack:_ +14 to hit, reach 10 ft., one target. _Hit:_ 15 (2d6+8) slashing damage.
• Tail. _Melee Weapon Attack:_ +14 to hit, reach 20 ft., one target. _Hit:_ 17 (2d8+8) bludgeoning damage.
• Frightful Presence. Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 18 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.
• Fire Breath (Recharge 5-6). The dragon exhales fire in a 120-foot line that is 10 feet wide. Each creature in that line must make a DC 21 DEX save, taking 70 (20d6) fire damage on a failed save, or half as much damage on a successful one.
• Sleep Breath (Recharge 6). The dragon exhales sleep gas in a 90-foot cone. Each creature in that area must succeed on a DC 21 CON save or fall unconscious for 10 minutes. This effect ends for a creature if the creature takes damage or another creature uses an action to wake it.

Legendary actions

• Detect. The dragon automatically detects every creature and trap within 30 feet of it, pinpointing the current location of each.
• Tail Attack. The dragon makes a Tail attack.
• Elemental Roar (Costs 2 Actions). The dragon roars at up to two creatures of its choice within 120 feet of it. Each target must succeed on a DC 18 CHA save or be vulnerable to fire damage until the end of its next turn. A target resistant to fire damage isn't resistant to it for the duration. A target immune to fire damage is still immune to it, even if the target fails the save.
• Wing Attack (Costs 2 Actions). The dragon beats its wings. Each creature within 15 feet of the dragon must succeed on a DC 24 DEX save or take 15 (2d6+8) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed without provoking opportunity attacks.

Special abilities

• Legendary Resistance (3/Day). If the dragon fails a save, it can choose to succeed instead.
• Suffocating Heat. As the **young brass dragon**, except it affects creatures within 30 feet of the dragon, and the save DC is 21.
