Earth soul

This sub class is based of stone sorcerer UA a few years back but I wanted to improve it.

Stones durability

At 1st level your maximum hp increases by 2, and it increases again every time you level up
As an action you can gain an ac of 13+con that last until dispelled with a bonus action

Extra proficiency

you gain proficiency with shields simple weapons and martial weapons
You can still cast spells even without a free hand if they have a weapon or sheild
Additionally you can speak read and write primordial

Earth spells

Starting at 1st level, you learn additional spells when you reach certain levels in this class, as shown on the Earthly Spells table. Each of these spells counts as a sorcerer spell for you, but it doesn't count against the number of sorcerer spells you know.

Whenever you gain a sorcerer level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be an abjuration or a transmutation spell from the sorcerer, warlock, or wizard spell list.

Geo sorcery

you can cast the spells gained from Earthly spells with sorcery points equal to the spells level when you do so chose one target of your choice that target has disadvantage on any saves to resist it

Extra attack

 you can attack twice instead of once if you take the attack option on your turn

And you gain tremor sense with a range of 30 feet

Master of the earth
