STRONGHOLD
2
This is the bread and butter of your success, upgrading this is important to be able to upgrade all of the other buildings. Not only does it give you power but it also increases your March Capacity which is important. Upgrading this will allow you to build much higher damage troops in your training camps. "This is a priority upgrade"

You should focus on getting this upgraded as much as possible, but if your just starting out on the game, get it to level 10 first and wait, as going past Stronghold level 10 will make you become unprotected as your shield will come off.

ACADEMY
4
This is where you do all of your research, whether increasing troops damage, building your defences or increasing resource gains. Try to max all of these out, there is no real set order for upgrading these, but getting extra "March Speed, Troop Load and March Capacity" as well as Troop attack and defences should be a priority in any matter.
5
EMBASSY
6
This is an important upgrade, as it increases your reinforcement capacity. This means any incoming attacks to your castle can be protected by your Alliance members by reinforcing you. The higher this building is upgraded to the more reinforcement troops are able to be sent to protect you. Winning battles is always what we aim for right? So get that baby upgraded as much as you can "This is a Priority upgrade"
7
HALL OF WAR
8
Another important building to prioritise, this building should always be maxed level to your Stronghold level. This increases your "Rally Capacity" the higher level this building is the more troops that can join in your rallies. More troops = more Power, so get this upgraded as much as possible. If you didn't know "Higher Rally Capacity Wins Wars" whether attacking or defending and is a crucial upgrade.
9
AIRSHIP DOCK
10
The Air Ship increases your power by alot and again is an important upgrade to max out. The reason we max this out is because upgrades to this building reward you with parts which are used to upgrade your Airship elements. Getting each element levelled to a certain level will allow you to upgrade the entire Air Ships power. Not only that it also bolsters your Troops stats and damage as well as increases your March speeds. Getting this as high level as you can is highly important. "This is a priority upgrade"
