How can I fight the blue dragon/change Odin to Raiden?
To fight the Blue Dragon, stand in front of the right throne in the ancient castle and take five steps south. You should be standing on the third set of stairs from the throne. If you hit the confirm button, you’ll hear a noise. Head to the right, where the Queen’s diary was, and there will be a new set of stairs. If you go down the stairs, you can fight the Blue Dragon, and also convert your Odin magicite to Raiden. Be warned, though, that you cannot change Raiden back to Odin.
