Rock Worm

These monstrous worms are a sickly brown colour and can grow over 15 feet long. Their powerful maw has three rows of teeth and can cut through rock aided by the strong acid secreted by glands in their mouth. In combat, the Rock Worm vomits this acid at its enemies. It is not uncommon to find gems and other ores in the stomach of these creatures after they have been slain.
