Taking 1 level of wizard lets you learn all spells from all spell lists and cast them as sorcerer spells including with metamagic. I learned haste from a scroll on my 2 wizard/10 sorc - then cast it using a level 3 sorcery spell slot and twinned it.
That's just broken. Apparently the multiclass system is full of problems like this, where you keep abilities even after you multiclass. Like the Warlock ability Necrotic touch which you can keep for free even after you multiclass.
So this is just an implementation problem and likely just an unfinished multiclass system.
I'd bet on it being intended. It's the exact sort of crazy combo thing Larian loves. Doesn't mean it won't be rolled back at some point if enough people complain, but I doubt it is just an oversight. Just speculation of course.
But yes, that is why I was saying that 2 wizard/10 sorc is likely the best all around caster.
No, that's just broken - given everything else I have seen in Act 3 it points to an unfinished system. Bg3 was released in an unfinished state - it's unfortunate but that is where we are right now.
I expect that they will eventually fix this and the many other exploits, cut content, and bugs in the game. In the meantime I wouldn't flex too hard on what is essentially an exploit. Our guild is banning the exploit like we do other exploits- tactician is too easy as it is.
