Primeval Lith Magic

The blood that flows through you shares a bond with the primal earth itself. You can feel it pulling and moving all around you and you see it pulsing with an energy that was there at the forming of the world. The force is so strong you can manipulate and conjure the ground you walk on and use the magic within the world to do your bidding.

Earth Link

Your bloodline has melded with the earth itself creating a sensory link you can tap into. This link provides you with the Tremorsense ability up-to a range of 30ft. You can also speak and understand the Terran language.

Rock and Stone

Your soul and skin hardens against both physical and magical effects, you gain advantage to constitution saving throws used to maintain concentration. As a Reaction when you take damage from an attack you can consume Sorcery points to create a temporary Earthern Shield around you. This shield grants you temporary hit points equal to 5 x number of sorcery points used. You can use this reaction a number of times equal to your proficiency bonus per long rest.

Tectonic Manipulation

The magic within you reaches deeper into the earth allowing you access to more of its primal power. When you deal magical bludgeoning damage from a spell or magical effect you can count any 1's rolled as 2's on the damage dice. You also gain the ability to use Earth Glide up-to your movement as an Action a number of times equal to your proficiency modifier each time you take a long rest and can burrow through nonmagical, unworked earth and stone. While doing so, you do not disturb the material you move through.
