SPECIAL ABILITIES

Adamantine Weapons (Ex)

The teeth and claws of a clockwork dragon are made of adamantine and have the qualities of a weapon made from that material.

Efficient Winding (Ex)

Built for long and dangerous missions, a clockwork dragon can function for 3 days per Hit Die each time it’s wound.

Self-Destruction (Ex)

When a clockwork dragon’s hit points are reduced to 10% of its total (17 in the case of most clockwork dragons) or less but are still above 0, the creature self-destructs on its next turn, bursting into an explosion of metal scraps and steam that deals 10d6 points of slashing damage plus 10d6 points of fire damage to all creatures within a 20-foot-radius burst. A successful DC 22 Reflex save halves the damage. The save is Charisma-based.

ABOUT

Environment any
Organization solitary
Treasure none

Puffs of steam, quiet hissing, and a whirring of gears accompany this massive metal dragon.

Though some scholars may argue about who exactly created the first steam-powered clockwork, the secret of their manufacture is now out. Savvy engineers have started to create faster and more powerful clockwork contraptions in the form of marvels blending arcane heat sources with large boilers to create pressured steam that powers the complex constructs.
