Traits

Damage ImmunitiesAcid

Legendary ResistanceIf the dragon fails a saving throw, it can choose to succeed instead.

Actions

MultiattackThe dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

BiteMelee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 6) piercing damage.

ClawMelee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.

TailMelee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage.

Frightful PresenceEach creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 16 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.

Breath WeaponsThe dragon uses one of the following breath weapons. Acid Breath. The dragon exhales acid in an 60-foot line that is 5 feet wide. Each creature in that line must make a DC 18 Dexterity saving throw, taking 54 (12d8) acid damage on a failed save, or half as much damage on a successful one. Slowing Breath. The dragon exhales gas in a 60-foot cone. Each creature in that area must succeed on a DC 18 Constitution saving throw. On a failed save, the creature can't use reactions, its speed is halved, and it can't make more than one attack on its turn. In addition, the creature can use either an action or a bonus action on its turn, but not both. These effects last for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a successful save.

How to actually run it

Tactics

The stat block tells you what it can do. This tells you what to do with it.

1Multiattack: The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

2Legendary Resistance means it can auto-pass failed saves a few times a day. Expect your first control spells to be shrugged off — plan around it.

3It is a legendary creature with 3 legendary actions between turns; fight it in its lair and it is far more dangerous than the stat block alone.
