Treasury

Treasury is a locked resource in all production buildings

The player cannot use it, but in the event of a successful siege, the enemy army can take it

The treasury is filled automatically when the resource is produced, with 90% of the resources going to the treasury and the remaining 10% going to the player's account.

The treasury usually generates Current Prosperity in proportion to the amount of the resource. For each resource, there is a coefficient of prosperity

food	0,5
wood	1
ore	2
weapon	3

When a resource is withdrawn during a robbery, the prosperity will also decrease but will not go in favor of the enemy and can be restored in the future when the treasury is refilled

In addition, the farm treasury is used to accelerate the maneuver of troops.

The size of the treasury grows during building upgrades, and it is proportional to the square of their level coefficient $treasury =level^2*10$
