How is my war base different from my village?

Your war base is very similar to your village, with a few exceptions. Your war base does not generate resources. The clan castle in your war base must be filled separately from the clan castle in your village. War bases never need to have their traps rearmed, defenses reloaded, or heroes healed, as they are always ready for battle. The war base can not be directly upgraded or rearranged, but will instead mimic the arrangement and highest completed upgrade levels of your village during the preparation day. Buildings and traps will never be “under construction” in your war base.
