I found that there is another folder where inside is monster.csv
I have unpacked the data.pak and found there is another monster.csv
You Can Finde it on:
\data\share\skill\creature\monster.csv
and you can see that file i have attached for you.
I also have attached Data.pak unpacker
I hope this can help you to create any hack and pls if you found something share with us like i do right now
