Some families are just natural spellcasters. Generations of sorcerer after sorcerer have come and gone. Now you are part of one of these families, and it is your turn to wield the magic inside you!

Extreme Concentration

You have honed your magical talent to a point where battle doesn't distract you from your spells. Gain the War Caster Feat, if you don't have it already.

Spellsense

Your constant exposure to magic has allowed you to refine the power inside of you. You gain proficiency with spell attacks.

Also, you can ignore all class, race, and level requirements when using magic items.

Sorcerers Eye

Your inner magic has grown to a point where it can alert you to unseen danger. If an unseen target makes a attack against you, you can use your reaction to magically alert you of the upcoming attack and to  make a DEX saving throw. On a failed save, the attack hits with half damage. On a successful one, not only do you completely dodge the attack, you fire a small, unavoidable, arcane bolt as a counterattack. This bolt deals 3d6 force damage and stuns the attacking creature till the end of it's current turn.

Spell Slot Breakthrough

Your magic has grown to a point where it breaks the boundaries of spellcasting. You can ignore spell-slots when you cast a spell. You can still use them for sorcery points.

Ultimate Sorcery

You have become a master of the magic inside of you. Gain expertise in spell attacks.

Also, you can use a bonus action to double the damage and duration of the next spell you cast. This feature can be only be used four times before a short rest is needed.
