+ finding Vincent +
+ Vincent can
be found in the basement of the Shinra Mansion in Nibelheim. To get the key
to the basement, open the safe on the top floor. The combination is right-36,
left-10, right-59, right-97, and you have 20 seconds to enter it correctly.
You then enter battle with Lost Number, and when defeated you will receive
the Odin Materia and the key to the basement.
+ Use the key to open the door to the side of the library. Vincent is there
resting in a coffin. Talk to him about Sephiroth, and then he'll return to
the coffin. Approach him again and he'll speak of Lucrecia, and then will
not speak to you again. Continue on to the library, and when you leave the
mansion, Vincent will decide to join your team.
