Any creature that starts its turn within 10 feet of the landshark takes 11 (2d10) fire damage.
The landshark's long jump is up to 40 feet and its high jump is up to 20 feet, with or without a running start.
The landshark sheds bright light in a 15-foot radius and dim light for an additional 15 feet.
Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 45 (6d12 + 6) piercing damage, and 14 (4d6) fire damage. If the target is a Large or smaller creature, it must succeed on a DC 18 Dexterity saving throw or be swallowed by the landshark. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the landshark, and it takes 42 (12d6) fire damage at the start of each of the landshark's turns. If the landshark takes 30 damage or more on a single turn from a creature inside it, the landshark must succeed on a DC 23 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 landshark. If the landshark dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 15 feet of movement, exiting prone.
If the landshark jumps at least 15 feet as part of its movement, it can then use this action to land on its feet in a space that contains one or more other creatures. Each of those creatures must succeed on a DC 18 Strength or Dexterity saving throw (target's choice) or be knocked prone and take 27 (6d6 + 6) bludgeoning damage plus 21 (6d6) fire damage. On a successful save, the creature takes only half the damage, isn't knocked prone, and is pushed 5 feet out of the landshark's space into an unoccupied space of the creature's choice. If no unoccupied space is within range, the creature instead falls prone in the landshark's space.
If the landshark is on solid ground, it melts the area around it, creating a pool of lava in a 10-foot radius. Any creature that starts its turn in the area or enters it for the first time on a turn takes 44 (8d10) fire damage.
