Sorcerer-Wizard and Opposition Schools

[Hopea]

So we're playing a campaign with quite a few freedoms given, such as 3.5 prestige classes.

So, I decided to go Wizard/Sorcerer/Ultimate Magus and therefore the question.

Do Wizard's Opposition School disadvantages apply to spellcasting from other classes?

That is, if I had say Enchantment as an Opposition School, would casting Charm Person from my Sorcerer spellcasting cost me two "charges" or what's the ruling on this?

Specialisation only applies to your wizard spells. Your sorcerer spells are treated as if your wizard levels did not exist. And vice versa.

Thank you, thats great news.
I currently happen to be the only Arcane Caster (only Spellcaster if you don't count the Ranger) so versatility is a big bonus to me. Which is why I'm willing to sacrifice some of my Wizard spell progression for the added versatility.

Mind you this also means your casting levels don't stack either.

Yes, True Magus helps some with that, there's a Trait for giving one class +2 CL (up to your HD), and since we get 3.5 material, Practiced Spellcaster Feat for +4 CL (up to your HD) for one class.

And ofc I went with the Sage Bloodline, to use INT instead of CHA for Sorcerer stuff.
