how to build exp bases and exp strongholds?
build at first an Expedition base cause you need coordinates for your exp. strongholds. IF YOU DONT HAVE THE COORDINATES YOU CANT BUILD THIS STRONGHOLDS YOUR SEARCH AFTER 6H WILL BE UNSUCCESSFUL.
after 15mins you will get reports in your mailbox. open it and you will see 6 coordinates (always 6) the first coordinate is your base, there you cant search successful so take the other 5.
1 Report = 5 exp strongholds.
tap on a coordinate, that will bring you directly to the place where you have to build. repeat this steps till your Construction points are full.
you can also build 2 exp bases but pay attention to the distance between both bases otherwise you will have the same coordinates in your second report.
your exp strongholds need 6h. after 2h you can see the first item that you get ( on the map), after 4h you can see the second and if your exp stronghold is been ready you can see all 3 Items in your report. the Reports are in your mailbox, tap on it and press claim prize.
take a look in your inventory, there you can see an item that name is old purse
in that are copper coins and gold.
Every day you can claim maximum 6gc !!!!!
