While concentrating for the duration, you can burrow through nonmagical, unworked earth and stone at a speed of 30 ft. While doing so, you don't disturb the material you move through. When the spell ends, you can be trapped and suffocate, therefore it is important to exit the stone before the duration ends if you are a creature that needs to breathe. While in the stone, your burrowing is silent. While gliding through the stone, you can't see what occurs outside it, and any Perception checks you make to hear sounds outside it are made with disadvantage.
Minor physical damage to the stone you are in doesn't harm you, but its partial destruction or a change in its shape (to the extent that you no longer fit within it) expels you and deals 6d6 bludgeoning damage to you. The stone's complete destruction (or transmutation into a different substance) expels you and deals 50 bludgeoning damage to you. If expelled, you fall prone in an unoccupied space closest to where you first entered.
