  • Bolstered By Carnage. If the lusca kills a creature, it gains advantage on its attack rolls and saving throws for a number of rounds equal to that creature’s Hit Dice.
  • Innate Spellcasting. The lusca’s spellcasting ability is Charisma (spell save DC 19). It can innately cast the following spells, requiring no material components:


  • Multiattack. The lusca makes seven attacks: three with its bites and four with its tentacles.
  • Bite. Melee Weapon Attack: +11 to hit, reach 20 ft., one target. Hit: 29 (4d10+7) piercing damage.
  • Tentacle. Melee Weapon Attack: +11 to hit, reach 20 ft., one target. Hit: 12 (1d10+7) bludgeoning damage.


  • Compartmentalized Minds. Any time the lusca would be charmed or frightened, it can instead cause one of its heads to fall asleep, negating the effect for as long as it would last and having one less bite attack for the duration. It still makes saving throws as normal for the effect.


A lusca 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. A reefhammer regains spent legendary actions at the start of its turn.

  • Grapple. The lusca makes a tentacle attack. Instead of dealing damage, the lusca grapples the target (escape DC 20).
  • Grind Bones. The lusca can damage one creature it has grappled as if it successfully hit with a tentacle attack.
  • Move. The lusca moves up to its speed.


On initiative count 20 (losing initiative ties), a lusca takes a lair action to cause one of the following effects; the lusca can’t use the same effect two rounds in a row:

  • A small whirlpool forms within a creature’s square that the lusca can see. That creature must attempt a DC 20 Strength saving throw or take 7 (2d6) bludgeoning damage and be unable to move on its next turn.
  • The currents within the lusca’s lair change and shift according to the lusca’s whims. Each creature within 60 feet of the lusca must attempt a DC 20 Strength saving throw or be moved 60 feet in any direction of the lusca’s choosing.
  • The lusca conjures one reef shark in a space within 30 feet of it. The reef shark is loyal to the lusca’s every whim and command.


The region containing a lusca’s lair is warped by the creature’s immense power, which creates one or more of the following effects:

  • Sharks and octopuses within 1 mile of the lusca’s lair become unnaturally aggressive, attacking any living thing they encounter.
  • Massive whirlpools begin to form within 5 miles of the lusca’s lair.
  • Currents within 1 mile shift and become supernaturally strong, pulling creatures caught within them towards the lusca’s lair.


This beast has three sharklike heads on short, scaly necks, while its lower body appears to be that of an octopus.
