This may have been asked before, but my sister and I have been wondering how to obtain the amiibo replica weapons (as in Marth's Spatha, Lucina's Estoc, etc.).
Before I got the game I had assumed you would get them if, you once had recruited the amiibo, they were running the weapon shop, but now I can see that blue shield units never appear outside of battle.
So how can they be obtained?
