Multiattack

The ziphius makes one beak attack and one claw attack.

Claw

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 14 (3d6 + 4) slashing damage.

Beak

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage. If the target is a Large or smaller creature, it must succeed on a DC 15 Strength saving throw or be swallowed by the ziphius. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the ziphius, and it takes 14 (4d6) acid damage at the start of each of the ziphius' turns. The ziphius can have only one target swallowed at a time. If the ziphius takes 20 damage or more on a single turn from a creature inside it, the ziphius must succeed on a DC 13 Constitution saving throw at the end of that turn or regurgitate the swallowed creature, which falls prone in a space within 10 feet of the ziphius. If the ziphius dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement, exiting prone.

Dorsal Fin

Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 20 (3d10 + 4) slashing damage.
