Hold Breath. While out of water, the CPUS can hold its breath for 2 hours.
Underwater Camouflage. The CPUS has advantage on Dexterity (Stealth) checks made while underwater.
Water Breathing. The CPUS can breathe only underwater.
Tentacles. Melee Weapon Attack: +6 to hit, reach 20 ft., one target. Hit: 13 (3d6 + 3) bludgeoning damage, plus 3(1d6) piercing damage. If the target is a creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and the CPUS can't use its tentacles on another target.
Ink Cloud (Recharge 6). A 30- foot-radius cloud of ink extends all around the CPUS if it is underwater. The area is heavily obscured for 3 minutes, although a significant current can disperse the ink. After releasing the ink, the CPUS can use the Dash action as a bonus action.
Description
Cephalopods of particularly unusual size is a rare sight, only known to most due to old fisherman's tales and legends of enormous squids dragging ships, large and small alike, to the briny depths of the sea.
