It's kinda weird. I thought the game would be patched but it wasn't so I'm using the previous trainer. (The updated trainer would crash the unpatched game) I'm going to assume that the Retail Game that was install = not patched yet despite being on Origin = All Clear for using unpatched version trainer.
From what I can tell, all the functions for the Origin version works. I should clarify one thing though, when I first install the game from the disk, it didn't work, despite the fact that you actually need to install Origin to register the game, etc., to start the game. Once I reinstall the game using Origin, it works.
ability point and skill point only works at the level up screen, and you have to enter and exit from the screen for it to take effect. Exp function will not level you up until you kill something in game to trigger it
