Caravaning

A great reason to reach lvl 41isplayers receive a vomitorium at this lvl. Caravans promote league properity! This building allows you to be able to carry out caravans, by clicking on other players and clicking the caravan button. Also, other players can send you caravans this way, and BOTH parties will receive money. There are however some little tips when it comes to sending and receiving caravans.
1 Do NOT lvl your vomitorium to start with, because it resets the caravans sent. You are only allowed to send 4 caravans each day, OR 4 each time you lvl your Vomitorium. So, each time you lvl your vomitorium , you are allowed to send 4 more caravans. That is why you do not want to lvl your vomitorium before sending out your 4 caravans each time. You can make good money lvling your vomitorium and sending caravans this way, till it reaches senatus lvl.

2 Who to send caravans to? The answer is easy. Send it to your friends and leaguemates. BUT, they will not want to send you their caravans if you have not lvled the other building you get at 41, the BathHouse. The bathouse is the building that allows you to make more money per sent caravan, it also means people will be more likely to send you caravans, because they make more money sending them to you. Don't ask for caravans if your bathouse (BH) is not lvled.3 The big money of caravans is receiving as many as you can. If you send 4, you make 4x however much your caravans are worth. That is of some value, but nonetheless limited. The big money is, when people send you caravans, you can make a ton more money by receiving 12 more caravans. 12 received caravans and 4 sent = 16 12+4=16x your caravan profit (which will vary depending on your other sender/reciever's vom +Bathhouse lvl)
Hypothetical 12+4= 16x 4,000=64,000

P.S. It may be you can only receive 8, I cannot confirm this number as of yet.
