Adamantine Claws (Ex)

The claws of an underworld dragon are made of adamantine, and have the qualities of a weapon made from that material.

Change Shape (Su)

A young or older underworld dragon can assume any humanoid form three times per day as if using polymorph.

Smoke Vision (Ex)

A very young and older underworld dragon can see perfectly in smoky conditions (such as those created by pyrotechnics).

Underworld Burrower (Ex)

An adult underworld dragon gains a 10-foot bonus to its burrow speed. When the underworld dragon becomes old and every two age categories thereafter, its burrow speed increases by an additional 10 feet.


Environment any underground
Organization solitary
Treasure triple

Underworld dragons, also called futsanglungs, are calculating, greedy creatures that carve great labyrinthine tunnels beneath the world, defending their hidden treasures. Preferring the earth to the heavens, they channel the fires of the world’s core within their twisting, stonelike bodies and through flaming breath hot enough to turn granite into slag.
