Special Traits

  • Blood Frenzy. The shark has advantage on melee attack rolls against any creature that doesn’t have all its hit points.
  • Water Breathing. The shark can breathe only underwater.


  • Bite. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 30 (4d10 + 8) piercing damage, and a Large or smaller target must succeed on a DC 18 Strength saving throw or be swallowed whole. If its bite attack is a critical hit, it can swallow a Huge creature in the same way. A swallowed creature is blinded and restrained and has total cover against attacks and other effects outside the megalodon. It takes 11 (2d10) bludgeoning damage and 11 (2d10) piercing damage at the start of each of the megalodon’s turns. A megalodon can have one Huge creature, up to three Large creatures, or up to 10 Medium creatures swallowed at a time. If the megalodon takes 45 damage or more on a single turn from the swallowed creature, the nightgarm must succeed on a DC 14 Constitution saving throw at the end of that turn or regurgitate the creature, which falls prone within 5 feet of the shark. If the megalodon dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 10 feet of movement, exiting prone.


The true nightmare of the sea is the megalodon, a shark that represents the pinnacle of this species’ evolution. Horrifying in its immense size and ruinous appetite, the megalodon is certainly the beast behind many legends of enormous fish who swallow ships whole. A megalodon is 60 feet long and weighs 100,000 pounds.
