Alright, I'll add those, and try to think of more. They'll be in their own category, labeled as 'usable by anyone', and everyone will get one of these spells at level 1.

Also, it appears as if I've miscounted, though your luck should be 4, you're actually correct with your intelligence. Dunno where I made my mistake. Well, that little oddity is fixed. Trolls now have +2 int, and +4 luck instead. Anyways, maybe a 'summon carrier pidgeon' spell would be a nice little add on to that list.
