I would like you to be a bit more specific than "all of them".
I'm thinking of something in the range of 10 to 20 extra spells.
I've attached a list of FRUA spells for you non-FURA folk, I'm sorry I didn't do that before.
As for rarity of spells, the designer can decide in the spell database if the spell is autoscribed upon gaining a new level or if it can even be scribed at all. This could be a spell that is only known by one NPC, etc.
