Smurf bot.

Looking for a bot that will level accounts for me. I remember seeing one that you could do 2-3 accounts per gb of ram but I cant find it. I want it to be afkable and to be able to do multiple accounts at once. I need it to be efficient, meaning it doesnt stop working randomly. It would also be nice if I had the choice to make it pick between aram and bot games if possible. If anyone knows of one that works nearly flawlessly please let me know.
