Special Abilities

Breath Weapon (Su)

A clockwork leviathan's breath weapon is a powerful jet of scorching steam-it functions equally well above and under water.

Grind (Ex)

A clockwork leviathan deals an additional 1d8+16 points of slashing damage when it makes a successful grapple check because of the myriad twisting gears and churning pistons that make up its jagged underbelly.

Swallow Whole (Ex)

A clockwork leviathan's interior is filled with injurious grinding gears and superheated water-in addition to taking damage, a swallowed creature must hold its breath or risk drowning as long as it remains inside a clockwork leviathan's "stomach."
 

Ecology

Environment: Any
Organization: solitary or pod (2-4)
Treasure: none

  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.
  Clockwork leviathans are 25 feet long and weigh just over 3 tons.
  Construction
  When creating these clockworks, great care must be taken to waterproof their components. The creator must start with crafted clockwork pieces worth 10,000 gp.
