And one final report for the day ... hope this isn't too much to deal with! This is more like a small feature request.
Once you've bought all the mage spells, should we have different text? Everything's functionally okay, but maybe a "we taught you all you could learn" as for when you learn a 3rd skill would be appropriate. Here's what I see after buying all spells. (Also, could/should "back" be detailed as "back to the main hall?"
