As for WoT, I think it'll be a lot easier to read the parts that people "don't like" because I don't have to wait at the end of, say, Book Ten for the next one.
Okay writers. Let's rate each others' first lines. First line of their book, a new character, whatever. I've got a silly one (which spawned the idea to make this topic in the first place):
Tavaris prayed, but received a monkey.
We haven't discussed Invested objects much. (Though its odd, since I was sure a Feruchemical charge is considered "Invested", but you can push on those)
The guessing about Szeth probably revolves around the fact that it is odd he has no spren.
You're quite right in that I don't know what Cultivation and Odium do. But then again, we don't have any confirmed instances of either of their magics, and what little we have is not particularly helpful for theorizing. So I'm not worried. It just comes from our lack of understanding.
