If a master makes a dish (food) with their blood, and their servant eats it, is it mana transfer and does the servant get mana, as a result?
Depends on the dish but I would say probably not? Cooking blood would make it no longer fluid, which seems to be a requirement for it to hold Magical Energy for a time after leaving the body.
Um, blood sausage.
Would it work???
What do you think?
