Pathfinder Deep Cuts: Adult Adamantine Dragon

Description:

The adamantine dragon - one of the skymetal dragons - got its name due to the adamantine covering its body. The magic that flows through them draws adamantine to their bodies like a magnet. These dragons can burrow through solid stone, emerging from the ground to ambush their prey. Instead of a typical dragon breath, adamantine dragons belch up huge boulders they consume while burrowing.
