Once you get into Bowerstone Market walk to Town Square. Once there you will find 
a potion shopkeeper on the left hand side. Walk around the right side of the buildings
there and down an alley to find a house known as Monster Manor. Sleep in this manor 
to gain its benefit (+1 star of Physique) Once you gain this benefit, go to your 
abilities list, select physique and hit Y to unlearn it. You will find that the bonus
 star from the house does not disappear, but the experience is given to you anyway. 
You can repeat this process over and over, the more stars you have in physique the 
more exp you get each time. This experience is general experience and can be applied
to any skills.
