Hemomancy
Blood magic, or hemomancy, is a school of magic based around utilizing blood as a material to cast powerful spells and curses. There is latent life magic in the blood of all creatures, though it is more potent in some more than others. Blood can be used to preform many things, such as healing spells, wards, damaging curses and complex rituals.
Blood as a Component
Hemomancy relies on blood as a spell component, In spell blocks this is represented by the blood component (B). The spell will list what the blood cost is to cast a spell, when you cast a spell with a blood cost you subtract that amount from your current hit points. To collect the blood for a spell you must use a ritual blade. Some spells may specify that the blood bust be from the target of the spell, if this is the case you must make a spell attack roll using a ritual blade. Collecting blood deals slashing damage
