Selecting Bruiser gives you 4 ST, after that you can remove all the bruiser given bonus and you will get your 4 points back if you have 1 ST. In-game this doesn't happen as far as I know. EDIT: nevermind, it happens in-game too. I also realised it doesn't let you go further in the CP.
Having 1 EN gives you 1 hp per level up. In-game this doesn't happen.
