GUIDE : GETTING TO CITADEL 20
The most important resource to get here is stone and energy!
I know ya’ll must have built more farms than anything else, but try to prioritize stone and energy.
The deal with upgrading your citadel is, you need 1 of each farm, quarry, energy extractor, mine, bank, hospital ward and barracks to be at their max level.
Example: if you are currently citadel 19, all of those need to be level 19 also before you can begin upgrading any other building.
TIP: DON’T USE EVERY RESOURCE ITEM IN YOUR INVENTORY! ONLY CLICK “USE” WHEN YOU ABSOLUTELY NEED THEM!
Every empire has a RESOURCE CAPACITY. You can check this by clicking on your farm/mine/quarry etc and it’s listed under EMPIRE CAPACITY.
Example: If your empire capacity for stone is 100k, and you have 1 million currently in your resource bar, YOUR QUARRIES WILL STOP PRODUCING THAT STONE UNTIL YOUR STONE GOES BELOW 100K. Leveling up all your quarries will increase the empire capacity.
