The claws of an underworld dragon are made of adamantine, and have the qualities of a weapon made from that material.
A very young and older underworld dragon can see perfectly in smoky conditions (such as those created by pyrotechnics).
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.
