Many of the quest provide a potion or book that will improve the base stats of the champion finishing the quest, however, the only time you can view the base stats is when the champion is leveling up, therefore, it is hard to decide whether to use the item or not since you don't know what effect the item will have on the overall behavior of the champion.  There should be a way to view the base stats from one of the screens.

Base stats are strength, intelligence, dexterity, etc. and not the information like attach, defense, combat speed, etc. that are shown on the character screen.

If there is already a way to this and I just not smart enough to figure out how to see the base stats I apologize and would appreciate if someone can clue me in.
