There's pretty important note missing. If you have plenty of levels and want to use high-level trainers and books first, just to don't miss or forget it later... Be extremely carefull. Because if, for example, if you have +2 racial bonus and you use book or med- or high-level trainer - you will lose point because of one or more of low-level trainers will be unavaiable. Learned that lesson hard way :C

You are WARNED I suspected this was possible however haddn't done any testing.. Thank you for the conformation MechaTC
