I have 2 questions, things I couldn't really find info about.
First, say someone did the first upgrade to a relic and then after that upgrade down the road they decide to change weapons. I know its not smart, but it probably has happened. Is there a way to get the currency from the first upgrade back? Do you have to do anything special to change weapons, or just bring the new stage one with items and initial currency to start the second weapon, even though the first one was not completed?
Any knowledge on this subject would be appreciated.
