Here I bring the Tibia MC (multiclient) to play with more than one account at once 100% undetectable.
NOTE: Not affected by the auto detect of bots, because it does not change the tibia client, so they will not ban you.
WARNING: If Windows Vista/7, Execute TibiaMC951.exe as Admin.
To use it, you extract the contents of the RAR into your tibia folder, then open as many clients as you want using the file TibiaMC951.exe
Manual with Pictures:
After Unzip files in the folder (C: \ Program Files \ Tibia)
Click on TibiaMC952.exe
Here we show how it really works.
