One with Stone
Urdunnirs have been blessed to move through the earth. You may use your bonus action to channel Dumathoin's power to walk through through unworked stone and earth as though it were air until the end of your next turn. You can carry up to twice your body weight with you in this manner. Urdunnirs (and anyone carried with them) cannot breathe while within stone or earth and must hold their breath while traveling in this manner. Once you use this trait, you can't use it again until you complete a short or long rest.
Handcrafter
Dumathoin's blessings allow Urdunnir the strength to shape stone and metal with their bare hands. You may use your hands as a set of smith's tools and mason's supplies, with which you are proficient. In addition, starting at 5th level, once per day you may spend 4 hours actively molding stone with your hands to cast the stone shape spell on that stone. When you reach 11th level you may also shape metal this way.
