Blood Binding

If a living creature dies within 30 feet of you, you may bind its soul as a full action on your next turn. You bind a spirit type of your choice to a spell slot of your choice. This binding expires after 24 hours or whenever you use this skill again. The creature who provided the soul cannot be resurrected during the time it remains bound. You may use this ability once, after which you must complete a long rest to use it again.
