A sort of magic class room would be nice - where you learn to know a "teacher" in form of a witch/mage with the unskilled dedication of Corinna the Summoner. A sort of tutorial for mixing spells, just so the gamer gets a hunch which possibilities she/he has - and the danger this has.

And this person pops up throughout the game when you try new combos.

Imagine: You're in the midst of a fight, you're in real trouble - this "Corinna" appears suddenly and blabs you full with all what you're doing wrong - how it should be done correctly - bringing you into more trouble.

Same could happen with a clumsy warrior teacher, when you try out new combat combos, lacking one skill or lvl etc - hitting your own party members.

Or a survivor teacher, telling you about the danger of creaking plate boots when you want to sneak or backstab - "displaying" what happens if you lack agility.

I think, these teachers could be permanent NPC, dreaded and feared, causing trouble and making the game not so easy (and a source for the Larian humour <img src="/ubbthreads/images/graemlins/badsmile2.gif" alt="" />).
