Traits:

  • Amphibious. The dragon can breathe air and water.
  • Legendary Resistance. If the dragon fails a saving throw, it can choose to succeed instead.

Actions:

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

  • Bite - Melee Weapon Attack:+ 15 to hit, reach 15 ft., one target. Hit: 19 (2d10 + 8) piercing damage plus 9 (2d8) acid damage.

  • Claw - Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 15 (2d6 + 8) slashing damage.

  • Tail - Melee Weapon Attack: +15 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 19 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.

  • Acid Breath - The dragon exhales acid in a 90-foot line that is 10 feet wide. Each creature in that line must make a DC 22 Dexterity saving throw, taking 67 (15d8) acid damage on a failed save, or half as much damage on a successful one.

Legendary Actions:

    The Ancient Black Dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Ancient Black Dragon regains spent legendary actions at the start of its turn.

  • 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 15 ft. of the dragon must succeed on a DC 23 Dexterity saving throw or take 15 (2d6 + 8) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
