For example, I have a hero with no Wisdom, he takes a Pandora box at level 1, then another Pandora box at level 2, and then an empty Pandora box... The question is, can I use a Town Portal scroll? The empty Pandora box could have contained the entire level 4, or it could have contained all the earth... If such a rule is to be introduced, it should only be done under the condition that any hero has learned a specific spell from the Pandora box.
