Special Traits

  • Amphibious. The lyngormr can breathe air and water.
  • Contamination. The lyngormr emits an aura of corruption 60 feet in every direction. Plants that aren’t creatures wither in the aura, and the ground in it is difficult terrain for other creatures. Any creature that starts its turn in the aura must succeed on a DC 26 Constitution saving throw or take 22 (4d10) poison damage. A creature that succeeds on the save is immune to this lyngormr’s Contamination for 24 hours. Bird eggs spawn more lyngormr instead.
  • Legendary Resistance (3/Day). If the lyngormr fails a saving throw, it can choose to succeed instead.

Actions

  • Multiattack. The lyngormr can use its Frightful Presence. It then makes two attacks: one with its bite and one with its tail. It can use Swallow instead of bite.
  • Bite. Melee Weapon Attack: +18 to hit, reach 15 ft., one target. Hit: 21 (2d10 + 10) piercing damage and the target must make a DC 26 Constitution saving throw, taking 42 (12d6) poison damage on a failed save, or half as much damage on a successful one.
  • Tail. Melee Weapon Attack: +18 to hit, reach 20 ft., one target. Hit: 19 (2d8 + 10) bludgeoning damage.
  • Frightful Presence. Each creature of the lyngormr’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 lyngormr’s Frightful Presence for the next 24 hours.
  • Poison Breath (Recharge 5-6). The lyngormr exhales poisonous gas in a 90-foot cone. Each creature in that area must make a DC 26 Constitution saving throw, taking 77 (22d6) poison damage on a failed save, or half as much damage on a successful one.
  • Swallow. The lyngormr makes one bite attack against a Large or smaller creature it is grappling. If the attack hits, the target takes the bite’s damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the lyngormr, and it takes 56 (16d6) acid damage at the start of each of the lyngormr’s turns. If the lyngormr takes 60 damage or more on a single turn from a creature inside it, the lyngormr must succeed on a DC 26 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the lyngormr. If the lyngormr dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.

Legendary Actions

The lyngormr 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 lyngormr regains spent legendary actions at the start of its turn.

  • Detect. The lyngormr makes a Wisdom (Perception) check.
  • Tail Attack. The lyngormr makes a tail attack.
  • Chomp (Costs 2 Actions). The lyngormr makes one bite attack or uses its Swallow.
