Oh right. I forgot to reply to that question:
Yea, Wizards that don't get new spells aren't as fun as ones that do. Each level you can add 1 spell that you can cast to your spell book. You, of course, can also add spells to your spell books by transcribing scrolls you find (or, should the opportunity arise, the spells from another wizard's spell book). But, each level, you get a free one (that will represent the product of learning and experimentation and the fruits of self-discovery).
