OK. I do have a plot hole now that is bugging me. This one I can't reconcile.
Sussur Bark and Flowers. Completely shuts off magic. You're a sorcerer, and you are seriously effected by this because you've had this wellspring of magic in you your whole life. There is even a cutscene for it making a big deal out of how you can no longer sense magic at all. It's totally messing with you.
So what's the explanation for the Sharran/Netherese Shadow Magic? This I can't explain. If it is a total antimagic force field around you, shutting down all magic, your tadpole should suddenly be free to munch your brain and turn you into a mind flayer. The Netherese Magic would be shut off too which was keeping it in stasis. Therefore, you should feel it suddenly spring to life and start to work on your brain and conscious mind.
But no. Taddy is completely unaffected by antimagic, just like everything else. MAN! That's one powerful tadpole. Even antimagic has no effect on it.
At first I thought sussur bark was actually creating an antimagic field. Per the
PHB - Page 117: "Antimagic Field ... Spells and other magical effects,
except those created by an artifact or a deity, are suppressed in the sphere and can’t protrude into it. ..." So by that line of thinking, I figured the tadpole might fall into the exception.
However, a little more digging into Sussur Bark specifically and I don't believe it actually creates an anti-magic field. Rather it is a plant that has learned to feed on the specific types of magic abundantly available in the underdark. IE:
Faerzress... which is in fact mostly limited to conjuration and divination magic. However if that is true, then spells belonging to other schools should still work. Hard to say if the final product will only disable those types of spells, or if they will go more the antimagic field approach. If the magic keeping the tadpolls in stasis turns out to actually be divine in nature, that might make more sense.
But yeah... ultimately, I don't think these things were thought out. The game has a number of plot holes... many mentioned in this thread. But so do most stories. One of my favorite is
The Lord of the Rings.... Maybe one day BG3 will get its own "How it should have ended" skit and we will all sit back and have a good laugh.
