Trying to stop the workings of cults, mages, and sovereigns obsessed with carving out dungeons beneath the earth is a lost cause but mastering how to traverse them is another matter entirely.
Bones of Stone
When you choose this circle at 2nd level, your bones become denser and increase your AC by 1. This bonus increases by 1 at 9th level and again at 18th level.
Starting at 2nd level, you gain an intuitive understanding of stone. Whenever you make an Intelligence (History) check related to the origin of stonework, you are considered proficient in the History skill and add double your proficiency bonus to the check, instead of your normal proficiency bonus. If you already possess this feature, you have advantage on these checks.
Beginning at 6th level, you gain a climb speed and are able to cling to stone or rock with only one limb (be that a claw, foot, or hand) even while using wild shape.
|5th||meld into stone, slow|
|7th||stone shape, stoneskin|
|9th||passwall, wall of stone|
At 10th level, while in contact with the ground you gain blindsight 20 feet. When you are underground your blindsight range increases to 40 feet.
Starting at 14th level, you are able to wild shape into an earth elemental with 100 hit points. At 15th level and every level thereafter your hit point total while in earth elemental form increases by 5 (to a maximum of 130 at 20th level).
