The Arcanum Vitae are rituals focused on making a person more than they already were, somehow. They don’t give their target any additional abilities or let them perform supernatural feats; instead, they “merely” enhance what is already present in that person, increasing their resilience, stamina, magical power, or ability to stay alive when pushed to the brink. They are, from a certain perspective, rather boring in their effects compared to the Arcanum Potentia or Sanguis, but some nations nonetheless consider them the mainstays of their military and magical preparations.
