The entire modding of Archeage is rather straight forward..
You simply use qbms to unpack the game_pak and also to repack it.
You can use unluac to reverse the .alb files in the scriptsbin folder.
If you didn't even notice, all of the edits that are done, are simply .lua files that are reversed with a .alb extension and the client accepts them ( we figured this out after realizing I wasn't even properly compiling my lua ^_^ durrr )
I give no credit to this author as most of what is done as a reverser myself, is rather straight forward and me and sullx have been taking apart all of the scriptsbin files bit-by-bit to see what is possible in the game as a whole.
So far, there is really no limits on how to do most of anything considering alot of this game is client sided.
I will write up a tutorial or if you are interested in contributing to it since there is so many files to go through, hit me or sullx up on skype! =)
