Love the character but as a drow I must kill her because she is weak in her belief that anything could be more powerful than Lolth.
I have a theory that the Absolute is Lolth's proxy, or at least they are allies. I have argued in this post:https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=717682&Searchpage=1
Minthara obviously does not know about this or about the tadpole. Although who knows, we'll see.
So don't rush to kill Minthara
It's not that simple with her.
