You buy land without putting things on it, then deplete your troops and then build something on that empty land. deplete your troops again and do it again. Over and over again. Building that building gives you some troops which will use less and give you full plunder.
When you explore a new land, if you build an attack building (with no troops) you can empty out but onlywith the atk gained from that attack building.
It can be attack or spy building. If attack, first explore new land. Then, empty all your soldiers and build attack building. You will get like 500 soldiers and b able to hit about 20 times with them(might need attack pots) Same with spy building except spy not attack.(duh) **Note** only build a lvl1 building. Do not upgrade before emptying troops the second time. After you have emptied troops for the second time, you can upgrade Also, land trick only works on a new land(;
heard wrong. its only on a new land. works best for a hansel, they can sell there old beast and put up guild there and then buy the next land and get another free unload.
