Bots..

I am just curious, how the hell they can play multiple accounts and farm spina or materials. For example in some maps of Toram like the ruins near the town where the bots farm then sell it to general store, how did they do that? Sorry for bad grammar

 

they run the game on an emulator program on pc. some emulators can run multiple instances simultaneously, and you can assign the same keyboard controls to operate them synchronised.
but bots usually run on macros (automated command input following a script), so they just need to set-up once and can run infinitely without any user interaction. a single macro can operate all instances at once if they use the same controls, so they can play on as many accounts as the hardware limit allows.
