Hello, just signed up to post my findings on this (especially as the full game is out next week and people may be looking for extra info)
First off, the gold trick works fine for me. It does act a little odd in that the game only allows stacks of 99,999, so if you try and split stacks that's the most you can get in a new one. Also, I did put 1 million in my personal sack, then tried to make a new stack and the million reset to 99,999. So be careful.
Second, I couldn't replicate the trick with changing stats & attributes above, but I did find my own way to get around it as you can also find your XP amount in ordinary values too.
Now, it may be tempting to simply put down 3 million XP, and indeed the game initially shows all the stats & attributes are available when you go to level up. But when you do, it all vanishes (just like mentioned above).
However, I've found you can simply set the XP to 1 below the required amount for the next level, then do something to increase your XP, and you get a level. You can even do this during a fight -
1: Set your XP to 1 below the next level
2: Kill an enemy, receive the XP and you level up
3: Tab out, set XP to 1 below again
4: Repeat with each enemy
I'll add the XP levels at the bottom of the post, for you to reference.
The addresses change, but for each character there are three addresses that contain the XP amount. Once you've narrowed it down (not difficult, I usually have it filtered down once I've found the first corpse then killed the first enemy) one of the values is the proper in-game XP - you'll know which one it is because the other two values change to match it.
It's actually quite quick to level up quickly this way - you can get to 20 before entering Cyseal proper.
There is one fairly big drawback with this, though - vendor inventories reset with each level up. That means that if you race to level 20, like I did, you'll find that you're stuck unable to get new skillbooks from them. So I'd recommend spamming your way to level 17, then check the vendors, level up once, check back, and so on. You should get all the good skills this way.
