The biggest downside to wizard is that there is very little reason to go several levels in Wizard. You only need 1 lvl to get access to every wizard spell in the game.
*tries to learn spell from scroll
"Wizard level is too low."
But you're not the only one making this mistake, just the arbitrary one I quoted.
I feel like many of you haven't noticed.
Often when you to learn a spell from a scroll on your wizard, it will tell you "wizard level too low."
Not just "level too low." Not "caster level too low." Specifically "WIZARD level too low."
You cannot just take a 1 level dip in wizard and learn all spells. You have to level specifically the wizard class high enough to learn that level spell.
So your one level dip is only you letting learn first level spells. Whoopty doo.
