Multiclass Wizard in 4e

[dextercorvia]

If you take the Multiclass Wizard feat, I get that it qualifies you for the Expanded Spellbook feat, but I'm having trouble understanding how these two relate. Do you automatically then get a Wizard Daily power for every level of Daily power you regularly posess, that you can then decide each day whether you want to 'prepare' that one or your class power. Or, do you have to wait until you have swapped out class dailies for wizard dailies (using Adept Power) to get any effect?

In either case, is it worth taking this feat combo? Or rather, which classes benefit most from this?

I don't think the combo works, because "preparing spells" is a class feature exclusive to wizards, that is not granted by the arcane initiate (wiz multiclass) feat.

So technically, you could take expanded spellbook and get more spells in there, but you couldn't actually memorize them.
