So, I played through 3.5 for some time and in that time I noticed, like many before me, that the system was just chalk full of the most broken and unbalanced things I've every expirienced in RPGs and is the major factor in me quiting the system. That said more than a few things still tickle my intrest that I never had time to try and was looking for a bit of direction concerning their balance in Pathfinder.
So, my question is this: what 3rd party source books don't break the system?
Specific books I was looking at that brought this to mind:
Tome of Magic
Weapons of Legacy
Book of Incarnum
