Here some suggestions I also had on the comments but makes more sense to put them here:
I would love to see something like an elemental affinity trait.
The idea is that if you use one element much more than any other you start building an affinity to this talent and the spells of that element get a little stronger while the direct opposite of that element gets weaker.
Example:
Fire Affinity: +1 Fire Based Spells -1 Water Based Spells
Earth Affinity: +1 Earth Based Spells -1 Air Based Spells
With regards to Talents:
Butchery talent:
The idea was based on the fact that you can bake bread in the game (as you said). That would imply that you can do some cooking. If that's the case then when you kill animals you should be able to butcher them for the meat and make some limited food out of it. That brought us to the topic of Weresheep and if it wouldn't be fun to have a secret recepie for Weresheep Roast you could find. That whole discussion lead us to having butchery as a trait, and that you could make your "Butcher" quest relevant by actually being able to learn the "butchery" trait from the Butcher if you chose an alternative ending for that quest. You might find out in the book in the Shelter at the End of time though that the Butcher does some pretty horrible things afterward. But that should be ok since you can always go back and kill him then =)
