Pact of the Blood Mark

Your contract with your patron takes a physical form as a mark made of blood on your body, that cannot be removed by any means. You choose an area in your body where the Blood Mark appears. While you have the Blood Mark in your body you can perform a 1-hour ritual to store a spell from your Warlock spell list that you can cast, but the spell can’t be higher than 5th level. You can perform the ritual once per long rest before you can perform it again to change the spell stored. Once you cast the spell you can’t cast it again until you finish a long rest. If you have placed the spell on a limp like an arm or leg and that limp get’s severed you can choose to instantly cast the spell stored using your reaction.
