Warriors Bloodline

Your magic comes from the manifestation of the fighting spirit within your soul, displaying itself in the form of raw elemental magic. Your magic may have come from a lineage of great warriors, or mabye it showed itself after many years of rigorous training in the ways of fighting. However your magic came about, it allows your strength and endurance to increase beyond the limits of what is normally possible.

Magical Barrier

Starting at first level, the magic within you protects you from harm. Whenever you finish a short or long rest, you gain temporary hit points equal to four times your sorcerer level.

In addition, the magic within you covers the exposed parts of your being. When you aren't wearing armor, your AC equals 13 + your dexterity modifier.

Arcane Strike

Also at first level, your magic alters your physical strength. At the end of each long rest, choose a damage type from fire, cold, lightning, thunder, acid, or bludgoening damage. Your unarmed strike will deal that damage type, as well as do 1d8 damage instead of the normal 1 damage. You can also use your charisma modifier in place of your strength modifier for attack and damage rolls for your unarmed strikes.

In addition, you learn the green flame blade or booming blade cantrip. It counts as a sorcerer cantrip for you, and it doesn't count against the number of sorcerer cantrips you know. Regardless of which cantrip you picked, you can use an unarmed strike in place of a weapon attack for the casting of both cantrips.

Arcane Flurry

At 6th level, your magic allows you to strike quickly after an initial attack. When you cast a sorcerer cantrip as an action, you can make one unarmed strike as part of the same action.

Warriors Flight

At 14th level, a pair of elemental wings appear on your back. They look like they're made out of the same element as your unarmed strikes (if your unarmed strike damage is bludgeoning, they may be made out of water, air, or earth, for example). As a bonus action, you can activate these wings for one minute. While your wings are activated, you gain a flying speed equal to your walking speed, your AC increases by 2, and your unarmed strikes do extra damage equl to half of your sorcerer level (rounded down). Once you activate your wings, you can't do so again until you finish a short or long rest.

Arcane Barrage

At 18th level, your rapid strikes hit with greater force. You can use a cantrip in place of the unarmed strike made with arcane flurry, and whle warriors flight is active, you can make a third unarmed strike as part of arcane flurry. This unarmed strike cannot be replaced with a cantrip.
