While the clockwork goliaths possess more brute power, clockwork dragons’ powerful breath weapons and mastery of flight make them more versatile and graceful killers. Designed for long flights and missions, the intricate winding mechanism of the clockwork dragon is more efficient than that of other clockwork constructs, partially because it reuses some of the energy generated by its intricate wings and the complex machinery of its breath weapon device. One of the most complicated and subtly crafted clockworks, its many moving parts are fortified by adamantine supports and fixtures, making this killing machine a brilliant mix of intricacy and unyielding terror.

The basic chassis and internal workings of the clockwork dragons are highly adaptable, and many variants of the clockwork dragon exist. Clockwork dragons are typically 20 feet long from snout to the tip of its tail, and weigh nearly 75 tons.

SQ difficult to create, efficient winding, swift reactions
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’ wound.

Self-Destruction (Ex) When a clockwork dragon’ 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.

Variant Clockwork Dragons

The following are a number of variant clockwork dragons. Some clockwork dragons exhibit more than one of these variations.

Acid Breath (CR +0): Equipped with an internal fountain of caustic liquid, this type of clockwork dragon replaces its fire breath with a 60-foot line of acid. Targeted creatures take 10d8 points of acid damage (Reflex DC 22 half ).

Destroyer (CR + 0): These clockwork dragons are used as highly mobile and powerful siege engines. While the destroyer clockwork dragon lacks a breath weapon, as a full-round action taken while on solid ground, it can move its gears to pull its wings apart and to rise up as a heavy bombard (Pathfinder RPG Ultimate Combat 161). The body of the clockwork is used as the platform for the bombard, and the internal workings of the clockwork can load the bombard without a crew, though it still takes five full-round actions on the part of the clockwork to load the bombard. The clockwork dragon can also take the actions necessary to aim the bombard. A clockwork dragon carries enough ammunition to fire the bombard 10 times.

Flaming Tar Breath (CR +1): Instead of breathing fire, some clockwork dragons spray a 30-foot cone of flaming tar. Creatures in the area of effect take 14d6 points of fire damage and are entangled in a thick layer of flaming tar. A successful DC 22 Reflex save halves the damage and negates the entangled effect. Creatures are entangled for 5 rounds as the tar burns. Entangled creatures take 3d6 points of fire damage each round on their turn. Spending a full-round action and succeeding at a DC 22 Reflex save removes the tar, freeing the trapped creature from the entanglement and further fire damage.

Infiltrator (CR + 1): These clockwork dragons are more subtle and nimble than those of other clockwork dragons. An infiltrator clockwork dragon can rearrange its movable parts into very serpentine and compact shapes, which gives it the compression ability. Furthermore, its parts are coated with a black, noise-dampening resin, granting it a +8 racial bonus on Stealth checks (typically Stealth +0). Finally, it’s infused with magic allowing it, as a standard action, to become invisible as the greater invisibility spell (CL 15th) three times per day. The infiltrator clockwork dragon’s invisibility is a supernatural ability.

Mithral (CR +0): This variant loses its adamantine weapons and its DR, which are replaced by greater flight capability thanks to its spell-infused mithral parts. Its land and swim speeds increase to 70 feet, and its fly speed increases to 200 feet with good maneuverability. In addition, once per day as a swift action, it can gain the benefits of the haste spell for 1d4 rounds.

Rust Breath (CR +0): Rust-breath clockwork dragons do not breathe fire. Instead, the creatures breathe out a fine mist of an alchemical solvent that instantly rusts exposed metals. This so-called ‘rust breath’ issues forth in a 60-foot line. Creatures can attempt a DC 22 Reflex save to avoid the effect for attended items; however, they need to make a separate attempt for each exposed item. Each alchemical dragon can hold enough of the alchemical solvent to make up to three breath weapon attacks before the solvent must be refilled manually, which takes 10 minutes. These clockwork dragons are made of ironwood, adamantine, and other resistant materials immune to rusting of any form.

Sleep Gas Breath (CR +0): This clockwork dragon’s breath weapon is replaced with tanks of sleep gas. When the clockwork breathes out this gas in a 30-foot cone, creatures within the cone must succeed a DC 22 Will save or fall asleep for 1d6+10 rounds. Clockwork dragons with this breath weapon tend to have either the infiltrator or mithral variants, and often they have both variants. These clockwork dragons excel at missions that require stealth and precision rather than brute force.


The clockwork dragon is a masterpiece of clockwork construction and is exceptionally difficult to create. The creator must begin with crafted clockwork pieces worth 25,000 gp.
