Blood Frenzy. The hybrid has advantage on melee attack rolls against any creature that doesn’t have all its hit points.

Brawn over Brains. When the hybrid attempts an Intelligence or Charisma saving throw, it may instead attempt a Constitution saving throw.

Underwater Camouflage. The hybrid has advantage on Dexterity (Stealth) ability checks while underwater.

Water Breathing. The hybrid can breathe underwater.


Multiattack. The hybrid makes a single attack with each of its attacks (if available). The hybrid can forgo making two of these attacks to instead take one other action.

Bite. Melee Weapon Attack: + 9 to hit, reach 5 ft., one target. Hit: 27 (4d10 + 5) piercing damage and the hybrid regains hit points equal to half the damage dealt (rounded down).

Ink Cloud (1/Short or Long Rest). A 40-foot-radius cloud of ink extends all around the hybrid if it is underwater. The area is heavily obscured for 1 minute, although a significant current can disperse the ink. After releasing the ink, the hybrid can use the Dash action as a bonus action.

Tentacles. Melee Weapon Attack: + 9 to hit, reach 15 ft., one target. Hit: 15 (3d6 + 5) bludgeoning damage. If the target is a creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and the hybrid can’t use its Tentacles on another target.
