Heart of Stone

You have become more in tune with the earth, granting you the following benefits:

-You have 10 feet of Tremorsense

-As a bonus action on your turn while you are standing on unworked stone or earth you can slip into the ground. You burrow 5 feet down instantly without disturbing the material you move through and remain there until the start of your next turn. While in the ground this way you are blinded, deafened, and unable to move. At the start of your next turn you re-emerge at any point of your choice within 10 feet of where you were when you burrowed into the ground. If any effect prevents you from being able to move, any attempt to use this bonus action fails. Once you use this bonus action, you can not use it again until you complete a long rest.
