The 6th city is really important because you will need the specialized troops that can only be trained there, and also to build the Atelier where a few processess are not available in the atelier in your 3rd city
From the super many attacks, can you see how many of those wanted materials were found?
Since yesterday's attacks still have not given me the sufficient number of materials needed, I attack again for today's turn.
So I don't show the rest of the loot since all materials are now enough.
