Force Mage

Your power comes from a long line of ancestors that have spent time in the Ethereal Plane, a space between worlds that requires the use of force magic to be effective. As such your force based magics are elevated to heights unknown to most others. In the past these ancestors have been referred to as Argent Savants, masters of force magic and abjuration.

Force Armor

Force Armor

Starting at 1st level, you can weave magic around yourself for protection. When you cast an abjuration spell of 1st level or higher, you can simultaneously use a strand of the spell's magic to create a magical ward on yourself that lasts until you finish a long rest. The ward has hit points equal to twice your sorcerer level + your Charisma modifier. Whenever you take damage, the ward takes the damage instead. If this damage reduces the ward to 0 hit points, you take any remaining damage.

While the ward has 0 hit points, it can't absorb damage, but its magic remains. Whenever you cast an abjuration spell of 1st level or higher, the ward regains a number of hit points equal to twice the level of the spell.

Once you create the ward, you can't create it again until you finish a long rest.

 

While Force Armor is active, has at least 1 temporary hit point left,  you have resistance to force damage.

Elemental Affinity

Starting at 6th level, when you cast a spell that deals force damage you can add your Charisma modifier damage rolls of that spell.

Force of Personality

At 14th level,  You gain immunity to force damage, and treat force damage immunity of other creatures as resistance. You also add your Charisma bonus to all saving throws. (include death saves: You own will forcing you to live.) 

Ethereal Survival

Beginning at 18th level, if you would die from any means, instead you reduce to 1 hit points and jaunted into the Ethereal Plane. While within the Ethereal plane you may treat your Charisma modifier as your Intelligence for any requirement. Such as movement. You may return to the Material plane as an Action. 

After this is used, you can not use it again until you finish a long rest, or cast a Abjuration spells of level 6 or higher, reestablishing your connection to the Ethereal plane.
