School of Blood Magic

You have studied the power of blood itself, and have learned to harness it's power as your own and empower your magic with it.

Blood Sacrifice

Beginning when you select this school at 2nd level, you can sacrifice hit points to cast a spell.

You can cast up to a level that you currently know at the cost of no spell slots. To determine how many hit points are expended, multiply the spell level by 10. ex, 1st level will cost 10 hit points, 2nd level will cost 20 hit points, 3rd level will costs 30 hit points, etc

If this causes you to fall to 0 hit points, you fall unconscious after the spell is cast. Spells cast in this way use constitution as a spellcasting modifier. 

Blood Bond

Beginning at 2nd level, you can bond to your spell book through a 1 hour ritual in which you must maintain contact with the book.

Once the ritual is complete, any spells you learn will take half as much time to learn. 

If a bonded spell book is destroyed, your maximum hit points are reduced by 1d6 until you bond to another spell book.

Starting at 6th level, You add the vampiric touch spell to your spellbook if it is not there already.
