Copper Dragon

Dragon · Huge

Copper dragons haunt dry hills, canyons and rocky uplands, where they run along cliff faces and lair in winding caves. They love jokes, pranks and tall tales, and a party that cannot laugh at itself may find its gear hidden or its path sealed with sudden mud. Hill folk swear that a good story told at a copper dragon's cave mouth is safer than any sword.
