Get multiclient, and Cotobo (ty chocoman...u pwn), and get like 5 miners going in pheonix castle...or maybe a couple in TC. No need to make a fancy pickaxe thats +9 with a socket, it doesnt make a difference. I'm pretty sure gem spots dont exist, but something i have noticed is that in all the super gems ive mined...they were all mined at 13:37 server time. I think its just coincidence, but it seems strange that ive found all my super gems at that specific time. Most definitely mine on the bottom floor, best way to avoid pkers, because it means more places for you to hide. To make it easy to remember where you left them for hunting down pkers/revive, put them starting (L L L) then (L L R) then (L R L) then (L R R), then if u have more, run them on the right side. It helps me to track down black names, or stupid rednames mining near me makin me log.
Its not much....as I guess im a dumb noob with no hacking skills (i only know HTML and javascript), but hey...at least im trying to contribute. Hope it helps!
Note: L=left, R= right.....
