Pindle bot runs on its own window, in diablo2 it uses auto mouse click to move a character down from act5 to a the red portal which is at the buttom of the town (the portal comes after you finish a certain quest) it enters the portal and wipes out all enimies in the small area, there is a special monster which is what the bot commands your character to kill than pick up the drops, pindle bot comes with the bot to pick up items, which can be set to pick up only certain types of items. To use the bot only a little information on inputing things into the program is needed.
Blizzard has loward the drop rate of the special monster in the area to combat the bot.
