L2Project became popular on the last server Mantosh and I played. Like any bot, it has it's pros and cons and it seems to work great on some PCs while being a resource hog on others. If you want to try it out you can download it here http://www.mediafire.com/file/cye8c2rtdb8xmq2/L2Project_-_Toggle.rar/file. Once you load up the EXE file, select the L2Toggle setting file and it will use the correct IP for login and server.
FYI, this bot is A M A Z I N G at quickly adding element stones to weaps/armor
