In the 2003 Anime Fullmetal Alchemist, in episode 45, she says that she had the Homunculi search for a Philosophers Stone because without Hohenhiem she was unable to create one by herself. But why?
Did she require knowledge that only Hohenheim had or was she simply not strong enough to do it? Because in a flash backs of Dante and Hohenheim's history, he did all the work, which would suggest that maybe she needed knowledge or strength or both, such as what Transmutation requires, but I'm not sure.
An answer would greatly be appreciated.
