Prerequisite: Spellcasting or Pact Magic Feature, 4th level
You can cast ritual spells that are on your spell list by expending and taking damage equal to one Hit Die per level of the ritual. Blood Rituals allows you to cast rituals that you may otherwise not been able to cast.
Whenever you cast a ritual spell that requires a material component, you can instead use blood, draining the living vital essence of creatures to power the magic in a unique way. Expensive material components may be replaced, with each additional hit die sacrificed in this manner able to replace up to 100 gp of material
components (for example, to replace a diamond worth 500 gold, 5 hit die would have to be expended in this manner)
