5+ Normal Gems a day, Usually around 15...
2+ Ref Gems a day
2+ Super Gems a week.
This is in Phoenix Castle (best place to mine imo)
I guess Ill post how I do it.
I run 16 miners, AND have a lag free main char.
For me, I have 2 Conquer directorys, one for mining, and one for my main char.
Open three clients at a time, log in the miners, set them to mining, then open three more clients, and ect.
Once all 16 clients are open and mining, if one of them dc's you can just relog it without killing your computer.
However if MORE then 1 client disconnects do NOT click both "Instruction - Error" boxs. Click only ONE, then relog that char, set to mine, and THEN relog the next char. Doing this prevents MASSIVE lag.
Im not sure why, but the "login" screen for conquer is what gives the lag. So make sure you dont have more then one login screen open, and you should be fine.
Also, when looking between miners for what disconnected, this is where opening in "groups" as i mentioned before helps. View the first three, then minimize them. View the next three, ect. untill you find the client that disconnected.
Opening ALL of the 16 clients at the same time WILL lag your chars, causing them to Disconnect, which slows down the mining process. (Long time mining with moving/disconnecting = less ores. Less ores = More Gems. This is the ONLY real mining trick)
Now some people simply cant open very many clients because their computer isnt very good. Mine isnt either so I guess Ill post my info.
