What spells and potions are you expecting?

I think there is going to be some sort of magical energy power bar (similar to the vampires’ purple bar) which is drained by doing spells. Apparently the use of familiars helps conserve this magical energy. But when I said I wanted magic to be costly, I also meant consequential. I hope spells take effort to learn and practice to master, as well as difficulty (in acquiring proper ingredients). In fact, I hope that without the right ingredients they won’t work so that sims must spend time finding and/ or cultivating them. I hope some spells or potions are permanent or long-lasting too (which it sounds like certain ones will be). One aspect of TS3 magic that used to annoy me was that some of the magic was so temporary (the Midas spell only lasted 6 hours for example), so I would prefer something more enduring in this game.
