How do I equip Weapons, Armors and Banners?
You can equip your regiment with an item by going on the Army tab and tap on the icon representing your desired regiment. In your regiment overview you will find three item slots at the bottom right side of your screen.
Just select the type of item you want to equip (e.g. a Banner) and a list of all items available in your inventory will be displayed sorted by relevancy (most recommended first).
Once you have decided which item you want to equip, hit the green Equip button on the item card. Equipped item will then immediately improve your regiment's attributes.
