I might be missing something, but a Cl11/Wiz1 can cast level 1 Wizard spells as far as I can tell. Even if they can up-cast using a level 6 slot (and I don't know if they can), it's still only a level 1 spell.
We don’t know if that is true. It seems Larian has changed how that works, but we don’t know the details.
