Tahmis: you're wrong on that one, I'm afraid. What I've explained above was a redistribution within a 'legal' limit, and BG2 will accept that no problem. When you redistribute within the level limits, games in general have NO way of knowing you've modified things at all.

What a relief Moggl !
I had started thinking in a new character...

Don't you worry, in theory, you could distribute your 6* to 6 single proficiencies (even though it doesn't really make sense) and the game STILL wouldn't know about it.
