If I want to start warring and I know I'm gonna need some towers. All I want to know is how many I need and how I'd get them. Would I explore more lands and build there or just replace some buildings? And should I just build spy defense or should I do troop defense as well?
Most clans require a minimum 2mil spy defense. You can do it anyway you want to but your best bet is to explore new lands and put towers down. HF lands are easy as they are cheaper starting out. If you replace current buildings then your plunder will drop faster. But each clan is differet in needs and best bet is to find a war clan to join and have them explain their needs.
