I found out about this exploit the week they made the skill changes. (Allowing the player to decide what skill they gain, lose, or lock.)
You know how there is a skill cap of 700 skill points
when you get it up to 700, you have to lose a skill to gain another one
Also you gain the most stats when the skill is at its lowest
which is 0-10
so get about 690 or so in your skill cap
have musicianship and arms lore at 0
practice arms lore to 10
thus you have a total of 700 skill cap
Then change the arrow so you lose arms lore
Then practice muscisianship to ten (which will alternatly lower the arms lore)
Do that back and forth
and your Str and Dex will sky rocket
and that takes about an hour
I've done this with all my characters
just interchange one of the skills with spirit speak or something to increase a different stat
muscisianship increases dex
arms lore increases str
spiritspeak increases int
I don't think to many people know about this bug
stat cap is 225
Have Fun!
