Wizard's spellbook

[Akarashi]

So, I've been playing around on the Character Builder in hopes of making a controller that I like. I've been playing around with a lv 10 ish wizard and every few levels, there seems to be a spell book selection in the powers page. Are these just additional powers or how do these work?

Spellbook is fully described in the phb on page 158. To sum up, you can store extra daily spells in your spellbook. After an extended rest, you choose which one you want to memorize, and that's the one you have for that day. It's a bit more than that though, I suggest you read the section thoroughly. Or, go to the class section of the CB, it describes it there as well under wizard in the sidebar.
