After a daylong ritual involving you and at least six others, one of whom must be a necromancer, you gain mastery of the blood.
Benefit: You may apply the bloodleech template to your spells. If you have cast a bloodleech spell in the past 24 hours, you heal naturally at an accelerated rate, recovering hit points equal to twice your character level with a night of rest, or three times your character level with an entire day and night of rest.
