Blood Cursed Sorcerer

Either due to the sins of your forefathers or through your own actions a curse has been placed on your bloodline resulting in a life of unluck and hardship. People and towns blame you for their problems and because of this you can never stay in one place for long. Whatever curse that dwells in your blood is powerful old magic that affects those around you in negative and unrelenting ways. Because your curse is constantly inflicting itself upon you, you have learned to hone your constitution to help fight off it's most adverse effects. Because of this Constitution is your spellcasting modifier. 

Dark Portent

Starting at 1st Level when you finish a long rest, roll two d10s and record the numbers rolled. You can replace any attack roll, saving throw, or ability check made by you or a creature that you can see with one of these foretelling rolls. You must choose to do so before the roll, and you can replace a roll in this way only once per turn. 

Fighting Style

You have been an outcast since birth and forced to fight your whole life. Starting at 1st level you can adopt one of the following fighting styles. 

Dueling

When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.

Thrown Weapon Fighting

You can draw a weapon that has the thrown property as part of the attack you make with the weapon. In addition, when you hit with a ranged attack using a thrown weapon, you gain a +2 bonus to the damage roll.

Two-Weapon Fighting

When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Aura of Ill omen

Starting at 6th level, whenever a creature within 5 feet of you must make a saving throw, the creature has a minus to the saving throw equal to your Constitution modifier (with a minimum bonus of +1). You must be conscious to grant this.

Heightened Dark Portent

Starting at 14th level, your visions of woe intensify. You can now roll three d10s for your Dark Portent feature or roll two d4s.

Form of Woe

At 18th Level, as a bonus action, you can expend 8 sorcery points to take on a form of curses themselves. You may choose one of the following options.

Slowed

• An unfriendly creature within 5 feet of you must use either an action or a bonus action, not both. Regardless of the creature’s abilities or magic items, it can’t make more than one melee or ranged attack during its turn.
  If the creature attempts to cast a spell with a casting time of 1 action, roll a d20. On an 11 or higher, the spell doesn’t take effect until the creature’s next turn, and the creature must use its action on that turn to complete the spell. If it can’t, the spell is wasted

Targeted

• Any unfriendly creature within your aura of ill omen is outlined in light. For the duration, affected creatures shed dim light in a 10-foot radius.
  Any attack roll against an affected creature or object has advantage if the attacker can see it, and the affected creature or object can’t benefit from being invisible.

False Visions

• Within your aura of ill omen, one creature of your choice suffers false visions of reality. They must make a wisdom saving throw at the start of each turn they begin in your aura. On a failure, any creature they target with an attack misses because they have perceived the creature to be in the wrong location.
