In the final area of Lacrima castle, you come across the pitch black tunnel, I'm sure anyone who can help knows what I'm on about, so I'll cut to the chase - how do you light the damn torch Fia spots with her magic?
Not sure if I'm right, since it has been a long time since I played Riviera, but I think you need to have a torch for that. If you got the brach earlier then lighted it, then you can light the torch.
