The Common Divine magic list is certainly useful... But I'd argue that sorcery is even moreso, especially since you can create your own spells. Make Logician into a ranged spell, and you've got something that's going to be used very regularly, and for a LOT of money!
If you have Logician, next step is to do something similar for other skills (or categories)... And, obviously, Enhance X.
Which brings me to a question (GM fiat)... Have all spells players could think of already been invented/created? Or are there some that can't be found anywhere? What about HQ - would anything a player can think of already be available to Lhankor Mhy, and thus could be taken as a,reward?
