Special Traits

  • Winding. A clockwork leviathan can function for two weeks every time it is wound. A creature of at least Medium size can use an action to wind the clockwork soldier, restoring to it 1 hour of operating time; a creature of Small size can wind it at half this speed, and Tiny or smaller creatures are generally unable to wind the leviathan.

Actions

  • Multiattack. The clockwork leviathan makes two attacks: one with its bite and one constrict.
  • Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) piercing damage.
  • Constrict. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage and 22 (4d10) slashing damage, and the target is grappled (escape DC 20). Until this grapple ends, the creature is restrained, and the clockwork leviathan can’t constrict another target.
  • Steam Breath (Recharge 5–6). The clockwork leviathan exhales scorching steam in a 60-foot line that is 5 feet wide. Each creature in that line must make a DC 15 Dexterity saving throw, taking 54 (12d8) fire damage on a failed save, or half as much damage on a successful one. A clockwork leviathan’s breath weapon functions equally well above and under water.

About

Clockwork leviathans are equally capable of functioning on land and in water. Sailors who are haunted by the memories of these treacherous machines need not exaggerate their yarns, for the reality of an aquatic construct such as this holds enough terror in its story for even the hardiest of seafarers. A clockwork leviathan’s numerous metal plates and links are made of such resilient material that they never rust, even after long exposure to the briny sea waters that leviathans often patrol like massive, eel-like dragon has two webbed talons. Its tail ends in large and powerful-looking flukes.

Clockwork. As a constructed being, a clockwork leviathan doesn’t eat, breathe, drink, or sleep. If it is not wound, it eventually becomes inert until it is wound again.
