An odd thought occured to me.
Are the bonus types tiered? Rather, what I mean is that most low level buffs are an enhancement bonus, and that it's often the higher level spells that allow for rarer bonus types (stacking with the much more common Enhancement and Morale bonuses) the seemingly most 'expensive' being Luck and Divine.
I haven't done any in depth research to see if this is the case, but if not so I've half a mind to implement such a system into my HB games.
