Farming forts- how?

It wasn't royalty, it was loyalty, and if you attack a fort 3 times in quick succesion you will take the fort (every time you win a battle against a fort it drops 40 loyalty, max loyalty is 100, and once it reaches 0 you take it as long as you have room for it)

Ahh that's some extra info right there! Now the question is, how u lower their loyalty down to zero at once??

You can't... Unless someone else has already attacked it and the loyalty wis at 40

Attack thrice within hour, command and relax. It will be urs. In simple terms
