Voodoo Sorcerer

You were born into an acursed family and being born into this family the curse was pushed onto you in a more physical showing. The curse granted you magical abilities in witchcraft to be specific voodoo and the manipulation of people and their physical self. 

Acursed Focus

Your spellcasting focus is a small doll made of straw. This doll takes the appearance of the target of your spells and the doll related abilities. The appearance shows any wounds on the person and what race they are. 

Level 3: Prick the Doll

When you cast a spell, using a straw doll as your spellcasting focus, using your magic action; you can cause a delayed prick, as part of the action, that deals an extra 1d4 of force damage on the enemies turn that causes the enemy, if they fail an intelligence save equal to your spell save DC, to flinch on their turn losing their bonus action. 

Bind

As an action you can squeeze the doll tightly binding the targets arms to their side grappling them until your next turn unless the target succeed a strength/dexterity check, they decide, equal to your spell save DC. During this grapple you can move them around a third of your movement plus your charisma rounded to the nearest multiple of 5. This can be extended with sorcery points. The first time costs one point, the second time it costs two, then the third time cost three.

Level 6: Break the Tension

When you trigger Prick the Doll you can instead heal an ally by 2d4 in 30 feet that you can see. This occurs on the allies turn. 

Level 14: Cursed Connection

You can now toss your doll as a free action and either command it, using your bonus action, to cast a damaging spell that deals half of the damage, this takes the spell slot below the spell the doll cast and then it returns to your hand at the start of your next turn or you can choose to teleport to the location of the doll, using your bonus action. This teleport gives you a plus 2 to your ac as well. This will cost you 3 sorcery points. 

Level 18: Perish Song

You stare at an enemy of your choice, intently, and wrap your hand around the doll's throat. You must hold concentration for 2 turns plus their constitution modifier and at the end of this the enemy must roll a constitution save (your spell cast DC + your charisma modifier + your proficiency bonus × 2) if they succeed they take 50% of their current health in force damage if they fail they get knocked out by suffocation. You can use this one every other long rest. This will take 10 sorcery points to use.
