spellcasting:
Starting at blood knight level one you have gained the ability to cast all spells from all classes using your own health, even spells that you don't know and spells from other classes. Using constitution as your casting ability, you take a number of one to eight damage dice rolls equal to the spell's level every time that you try to cast a spell. As an addition to this system, all attack spells that successfully damage enemies deal an additional number of one to four damage dice rols equal to the spell's level. Casting cantrips works normally with constitution as your spellcasting ability. You can't cast healing spells on yourself.
Your spell attack save is equal to your constitution modifier modifier with your proficiency bonus.
The spell save difficulty class is equal to eight with your constitution modifier and your proficiency bonus.
class features:
Crimson Vulnerability
It may be difficult to hit you, but the damage that is done to you is amplified. Whenever you get attacked by an enemy, you take twice as much damage.
Blood Link
You have developed the ability to telekinetically leech blood from your breathing enemies. On one of your turns, you can choose to form a blood link with one breathing creature that you see to gain 1d20 hit points on each following turn until the blood link is broken. On each turn that blood link heals you for 1d20 hit points, the creature that blood link is being used on takes one point of damage. Blood link is broken when you attack any enemy or cast any spell.
Sanguine Charity
At blood knight level one as an alternative to ordinary healing spells, you can choose to donate a specific number of your current hit points to a party member directly. You can do this freely multiple times for multiple party members without needing to take any actions, bonus actions or special actions during your turns.
