Hey boys,

 

Does someone already reversed that one? I need it

It is not reversed, but seems to work just fine (https://metin2.download/picture/2vYkRa9le60NGVOjaxlz81nad7RJoDNG/.png)

I don't think so that this will help you, but here it is what you asked for.

Btw this code has been completely removed after the renewal of the pendant system. They changed the way of the system, for monsters the values are inside the mob_proto, and for players: the second parameter of the CPythonNetworkStream::SendTargetPacket function requests the data which will be loaded from the server through packet (CPythonNetworkStreamPhaseGame.cpp[CPythonNetworkStream::RecvTargetPacket] --> game.py[ShowTargetElementEnchant] --> uitarget.py[ShowElementImg]).
