Earth Specialization
Elemental specialization for earth and stone.
Rank 1: Stone-Flesh
Universal Trait
Add ranks of homogeneous armor, equal to your ranks of elementalism.
Rank 2: Rooted
Universal Trait
As long as the creature is touching the ground, it becomes immune to pushes, or forced movement, that would not also move a substantial chunk of the ground as well. Furthermore the creature's shock value is doubled.
Rank 3: Hole in the ground
Earth Trait
The Earth elemental can now burrow through any unworked earth (including stone) and can leave a trail behind it. When burrowing, it can pull objects from the stone it's tunneling through, but may damage some of the stone in the process.
Rank 4: Wall of Earth
Earth Trait:
The creature gains a supernatural level of control over the rocks and earth around it. When it is not helpless, and standing on ground it could move through, the creature can interject a sudden wall of earth between itself and the attack. Giving it a shield rating, equal to 2x your elementalism. (The shield bonus can not be greater than the creature's body). The Creature can now also make walls, as well as tunnels, though it doesn't necessarily understand how to keep them standing.
