Noob Doubts

Don't quote me on this but I think you can get rewards from bond on both. Idk why you would want to bother though, you'd never have enough time to get all your servants to a high enough bond level for decent awards, and you can't put more than 1 copy of the same servant in your party, so it seems pointless to level duplicates for bond rewards : /

That would be a no, I can confirm this as I have a max level georgios and a lv 1(for soloing), they share bond levels
