I think its difficult nowadays, to get a professional und undetectable Bot for Metin2.
In a few cases, you have a bot that only works until the next patch and then no longer works. In worse cases, you still have a backdoor in your PC or a keylogger. In addition, the metin2 community is unfortunately becoming smaller and smaller, which means that fewer and fewer people are dealing with these types of projects. What I can recommend is to write your own bot, use the tools provided and see how you can get the best out of it, otherwise you'll just be taking the risks mentioned above.
