I don't know if this is known publicly so just a really really short guide how to make Cheat Engine work with archeage.
I for myself have not enough time to find out what to do with it, but I'm sure you can do a lot of things with it like tp hack and speedhack quite easily. Other things like droprates might also be possible I HAVE NO CLUE but a lot is client side in this game.
So first you need cheat engine. Download and install it. Then open Cheat engine.
Click on Edit(left upper corner of the cheat engine window)->Settings->general settings.
Then write into the field where "Automatically attach to process name:" archeage.exe
Click ok. Now when you start archeage you can scan for values or whatever you wanna do.
But make sure to always start Cheat Engine before you start archeage.
I'm interested in what's possible in this game because i know from other mmos that only with cheat engine a lot is possible.
Have fun
