Stoneheart

Blessed with natural resilience and command over the stones on which they stand, most of these sorcerers are solid and deliberate in both action and thought, slow to act, but once set on a course they become stubborn and immovable from their chosen path.

Steadfast Proficiencies

At 1st level, you gain proficiency with shields, simple weapons, and martial weapons.

Stone Aegis

When you choose this Origin at 1st level, your form begins to harden, giving you considerable toughness and durability. As a bonus action, you can summon a rocky aegis around you that lasts for 1 minute, or until you use this ability again. This aegis is a visible defensive aura, though it's appearance may vary.

While you are surrounded by the aegis, damage taken by you is reduced by your Proficiency bonus.

Skin Of The Earth

At 1st level, your skin is as tough as stone, sometimes even bearing rocky protrusions or rock-like texture. When unarmored, your durable form grants you an AC equals 10 + your Constitution modifier + your Charisma modifier.

Encompassing Aegis

Starting at 6th level, when you activate your Stone Aegis, you can expend 1 sorcery point to target an additional allied creature within 60 feet. When you do so, for the duration of that aegis, both you and the target creature gain the benefits of the aegis.

Additionally, when a creature protected by your aegis is struck, the absorbed impact is stored until the end of your next turn. The next melee attack you make gains advantage; and if it hits, it deals an additional 1d6 damage. Your aegis can store 1 hit at a time (to a maximum of 1d6 damage).

Stonewalk

Starting at 14th level, you gain a burrowing speed of 15 feet, allowing you to travel through the earth. You can pass through soil and stone, but when you pass through stone you leave no hole behind you, becoming one with it and passing through. If you would end your turn inside of stone, you get pushed to where you entered the stone surface.

Earth's Embrace

Starting at 18th level, your aegis can be extended to additional targets up to a number of targets equal to your Constitution modifier. Your aegis can store additional hits, increasing the damage of your next melee attack by an additional 1d6, to a maximum of 5 hits (dealing 5d6 additional damage on your melee attack roll before the end of your next turn).

Additionally, you have advantage on Constitution saving throws.
