It would be better to add a library, trees that boost stats, and wisdom, because magic has become a bit dull.
A library?? Could you elaborate on what that is (I'm used to English, so I didn't recognize the building).
Trees that give levels?? They already exist.
Wisdom? Well, the magic system has undergone changes, and the skill itself, by the way, has remained, but now it only allows you to learn any 3rd-level magic without magic schools.
