Academy

The academy is a building in warbanner

The academy allows you to do research using science points, it contains 4 tabs: military, economic, orders and fortifications

Military
the military tab allows you to upgrade your regular and national troops, however, this has serious drawbacks, it will make cost far higher and may even add new resources (example:line infantry level 2 starts costing Wood too), and even after that, all enemy units of the same type that bots spawn will have a higher level than usual too, it is unconfirmed if its equal, 1 or 2 levels lower than the player's infantry

if you play in kongregate.com this is NOT recomended (this may be worth leveling a few times only on national troops, on high levels such as 30-40, depending on your playstyle)

Economic
this tab contains upgrades for your production buildings, storage capacity and special things below the town hall picture, and upgrades to reduce cost and training times of mainly military things in second page, taxation is located here

Orders
this tab contains upgrades for your orders, every order will be able to be upgraded with an increase to reload speed and effect (by example damage)

Fortifications
this tab contains upgrades that increase the stats of the fortifications defending your city, it is unknown if it will bring effects like making bots defenses stronger, this is not recomended for now if you play at kongregate.com
