Rockslide Drake

From publisher blurb: The bane of Dwarven mountain settlements, rockslide drakes are predatory relatives of dragons that ambush prey with artificial landslides. Covered in thick scales that match the stone of the mountains they call home, they spend much of their time basking in the sun and preparing ambush spots using its acidic saliva. In combat a rockslide drake is a whirling mass of horns and claws, shattering rock formations with a slap of its tail and covering the battlefield with deadly shrapnel and rolling boulders.
