Traits

Amphibious. Rokobakaniceva can breathe air and water.

Adaptive Camouflage. While motionless in water, Rokobakaniceva is indistinguishable from coral or rock (DC 18 Wisdom [Perception] to discern). When it first emerges from hiding, it has advantage on attack rolls until the end of that turn.

Holdfast. As a bonus action, Rokobakaniceva can anchor up to four of its tentacles to solid rock or reef. While at least four tentacles are anchored, it can’t be moved against its will, and it is immune to the grappled and restrained conditions. Releasing or re-anchoring any or all tentacles is a bonus action.

Actions

Multiattack. Rokobakaniceva makes three attacks: two with its Tentacles and one with its Beak.

Tentacle. Melee Weapon Attack: +12 to hit, reach 20 ft., one target. Hit: 18 (2d10 + 7) bludgeoning damage, and the target is grappled (escape DC 18). Until this grapple ends, the target is restrained. Rokobakaniceva can grapple up to four creatures at a time.

Beak. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 27 (3d12 + 7) piercing damage. If the target is grappled by Rokobakaniceva, the attack deals an extra 10 (3d6) damage.

Reef Shatter (Recharge 5–6). Rokobakaniceva slams all anchored tentacles into the seabed, triggering a shock wave. Each creature of its choice within 30 feet that is in contact with the same body of water must make a DC 19 Constitution saving throw. On a failure, a creature takes 36 (8d8) thunder damage, is knocked prone, and drops any creature or object it is holding. On a success, a creature takes half damage and isn’t knocked prone. Vessels in the area automatically take the full damage.

Bonus Actions

Constricting Drag. Rokobakaniceva moves each creature it is grappling up to 20 feet toward itself. A creature that ends this movement adjacent to Rokobakaniceva is pulled 10 feet underwater (if able).

Reactions

Ink Burst. When Rokobakaniceva takes damage, it can eject ink in a 20-foot-radius cloud centered on itself. The area is heavily obscured for all creatures except Rokobakaniceva until the end of its next turn.

Legendary Actions

Rokobakaniceva can take 2 legendary actions, choosing from the options below. Only one legendary action option may be used at a time and only at the end of another creature’s turn. It regains spent legendary actions at the start of its turn.

Tentacle Attack. Rokobakaniceva makes one Tentacle attack.

Relocate (Costs 2 Actions). Rokobakaniceva swims up to half its swim speed without provoking opportunity attacks.

Crushing Beak (Costs 2 Actions). Rokobakaniceva makes one Beak attack against a creature it is grappling.

Lore

A deity in the form of an enormous octopus.

Rokobakaniceva, a gigantic octopus deity, holds sway over the oceanic realms. He stands as the eternal guardian of the Naceva Passage off Kadavu’s southern shore, where he maintains the balance between humankind, the sea, and all other ocean-dwelling creatures.

Rokobakaniceva is portrayed as a colossal octopus whose immense size and physical presence inspire awe. The most striking feature is his eyes—described as intelligent and wise, their gaze conveying awareness. This detail underlines his sentience, setting him apart from an ordinary sea monster.
