Baal bot is designed to give the botter and everyone else xp. I creates a public game with no password, then it teleports to Baal's throne while everyone comes into the game. It clears a spot in the corner of the throne room (and says "Clearing tp spot" if you set it to), opens a TP for the other players to come in and get XP (and says whatever you set it to say when tp is up), then it proceeds to kill all of the minions. After the minions are dead you can set it to either make NG and do it all over again or go in and kill Baal (for MF) and then make NG. It will chicken if it reaches a life amount you set, or you can also set it to chicken on dolls/souls, you can set it to chicken if your merc dies, lots of different things... you can set it to tele to a corner after a3 minions are dead to avoid being hit by hydras, and to go to town to heal after you get poisoned by a2 minions... its all very configurable. As far as if people don't join, it just does the run alone.
