Bloodshaper

Hidden in the recesses of our blood lies magic, in a way that strengthens magic and in a way that magic may strengthen it. Your desire to access this has led you to become a bloodshaper, one who has access to the reins of the magic in our blood. Undergoing a dark ritual you have tied your blood to the magic inherent in all blood. Now you can use that to manipulate blood, both yours and others.

Stem the Blood

Your knowledge and control of blood aid you in helping others. At level 3 you gain advantage on all medicine checks.

Blood Armor

Starting at 3rd level you may touch a creature. Until the end of your turn, immediately after dealing sneak attack damage, you may draw the blood out from the creature you damaged and move it to form armor over the creature you touched. They gain tempory hit points equal to your sneak attack damage. You can use this feature a number of times per day equal to your constitution modifier.

Blood Pact

Starting at level 9, immediately after dealing sneak attack damage you can damage yourself equal to one sneak attack die you rolled. Mixing the your blood with your enemy's you create a bond between yourself and the creature you damaged. You can move your blood and force them to move theirs. For the next minute, they gain disadvantage on any attack rolls made to anyone other than you.

Freeze the Blood

Starting at level 13, you can attempt to control the blood in a creature's body. Although you cannot puppet a creature, the ability to fight against their will for control is enough. Roll a constitution vs their constitution save. If you succeed, until the end of their next turn, both you and that creature are immobilized. You can use this a number of times per day equal to your proficiency bonus.

Blood Weapons

Starting at level 17, immediately after you deal sneak attack damage you can form the blood spilt into weapons and attack a nearby creature with them. Roll your sneak attack dice again and deal that damage to a creature within 5ft of your original target. You do not need advntage against the new creature.
