I'm not an expert on this, but I'm gonna try to explain.
Cells/Pads represents which screen of the room you are.
You use than to make a bot which your character "jump" screens to reach the monster that you want to kill.
EX: Battleon main screen Cell/Pad is Enter,Spawn. If you go to the second screen(go up) the Cell/Pad will be Enter2,Spawn.
