This question already has an answer here:
So I've watched FMA: Brotherhood and Star of Milos. I want to watch conqueror of Shamballa but it seems like it continues from the original series. I don't want to have watch the original series since I know that the earlier portions of the story are the same as Brotherhood . Is there an episode in the original series I can start watching from that's starts to have a different story path from Brotherhood? Or should I just read about the originals ending?
