SPECIAL TRAITS

• Regeneration. The atuikakura regains 10 hit points at the start of its turn. If the atuikakura takes lightning or slashing damage, this trait doesn’t function at the start of the atuikakura’s next turn. The atuikakura dies only if it starts its turn with 0 hit points and doesn’t regenerate.
• Water Breathing. The atuikakura can only breathe underwater.

ACTIONS

• Multiattack. The atuikakura makes one bite attack and two tentacle attacks.
• Bite. Melee Weapon Attack: +14 to hit, 20 ft. reach, one target. Hit: 31 (4d10 + 9) piercing damage plus 27 (6d8) poison damage. If the target is a creature, it must succeed a DC 18 Constitution saving throw or become poisoned and blinded as they hallucinate from the atuikakura’s poison. A creature can repeat the Constitution saving throw at the end of each of their turns to end these effects.
• Tentacles. Melee Weapon Attack: +14 to hit, 20 ft. reach, one target. Hit: 14 (1d10 + 9) bludgeoning damage.

REACTIONS

• Self-Evisceration (3/Day). When an atuikakura takes damage, it can reflexively expel extraneous respiratory organs from its body, poisoning and entangling a nearby foe. A creature up to 20 feet away (or up to 10 feet away if the atuikakura or the other creature is not underwater) must succeed a DC 18 Dexterity saving throw or become restrained and a DC 18 Constitution saving throw or become poisoned for 1 minute. A restrained creature can attempt a DC 18 Strength saving throw at the end of each of its turns to end the condition.

ABOUT

Atuikakuras are typically content to dwell placidly at the bottom of deep bays or oceans. They are easily startled by large objects and creatures and enjoy entwining themselves around driftwood and other solid objects and resting there beneath the waterline, which can lead to rare attacks on ships or other surface dwellers.
