Echolocation. The bake-kujira can’t use its blindsight while deafened.

Keen Hearing. The bake-kujira has advantage on Wisdom (Perception) checks that rely on hearing.

Leviathan’s Wail. As a bonus action a bake-kujira can sing a haunting tune. Living creatures within a 120 feet must succeed at a DC 18 Charisma saving throw or gain the charmed or frightened condition (decided by the bake-kujira when it sings) until the end of the bake-kujira’s next turn.

Pain Threshold. Any attacks or spells that deal 10 points of damage or less do not deal any damage to the bake-kujira.

Undead Parasites. A 30-foot radius cloud of undead fish and sea birds surrounds a bake-kujira. Creatures starting their turn within the cloud must succeed at a DC 15 Wisdom save or take 21 (6d6) necrotic damage and gain the poisoned condition until the beginning of their next turn.

Actions

Multiattack. The bake-kujira makes one bite and one tail slam attack.

Bite. Melee Weapon Attack: +15 to hit, reach 20 ft., one target. Hit: 115 (10d20+10) piercing damage.

Tail Slap. Melee Weapon Attack: +15 to hit, reach 25 ft., one target. Hit: 65 (10d10+10) bludgeoning damage.

Resonating Song (Recharge 4–6). The bake-kujira lets loose a powerful song in a 60-foot cone. Each creature in that cone must make a DC 18 Constitution saving throw, taking 90 (20d8) thunder damage on a failed save, or half as much damage on a successful one. Any creature that takes 50 or more damage from the bake-kujira’s resonating song gains the deafened condition.

Description

The pirates at the edge of the world have many stories and myths, but the most feared legend is the bake-kujira. This enormous whale swims the oceans around Soburin in search of ships to capsize, wandering without rhyme or reason and leaving nothing but destruction and horror in its wake. While the colossal monstrosities were once rare and few, with the return of the Mists of Akuma they have become a far more common occurrence and are now cited as the cause of many a coastal town’s curse—even the poor souls who merely witness its passing are said to be doomed to an early, gruesome demise.
