Changing building level needed for units?

[DarkLordFollower]

So when I look at the barracks I notice that the barracks for Castle is nearly identical to the Wooden Castle barracks, as in I gain no new units. The barracks for Fortress on the other hand gives about 4 new units!

How can I edit at what level each unit can be trained?

You need to edit the export_descr_building.txt file. You can have a look in this tuto.

I don't need to know everything about the file I just need to edit 1 building

The problem is not to edit the building but which units, their factions owners, their avalability, their replenish rate, and so on for that specific building. If you don't understand how that file basically works, you won't be able to do it yourself or not in the right way.

I'll see if I can make or find something quite simple for your request.
