I haven't played Metin2 for a while, but now I'm back. I played with your hack before, like in 2013, and it had an window on F5. Where is it ? I need that item stealer, because I can't find another one.
Oh, and I have a suggestion:
1. The react delay should by like a time between X and Y .
eg. : 2.50 - 3.0
Why ? Because this way you can't get banned by the system.
2. Add a mob caller button in addition with the existing one. Just tot click on it, and call the mobs a single time.
Anyway, your hack is the best ! Good job :)
