Farming is when you set up a room with AFK accounts, and you just kill them all with your main account to gain EXP.
Possibly there are working Farming Bots Hack but they are not sharing it.
Or you can buy multiple laptops to Farm.
That's exactly right.
And yes, there are farm clients, but we don't have any released at the moment... So if you wanted to farm, getting more PC's or waiting for a new farm client to be released is your current options at the moment...
