first of all it won't do good to basic sniff packets because they are encrypted. You should look into figuring out the encryption pattern and then can hit the ground running.
if you try and hit this head on without any prior knowledge its going to feel like this
now this is the hard truth. This is not the FlyFF everyone knows. it is completely different complete with quests, items, spells and much more. If I had the time I would make a project of this but until someone cracks the encryption its not high on my list.
for the record, the picture is a personification and not necessarily how I feel. Enjoy how you see fit.
