What's the tallest Large Underworld possible? I've had my Expert one that starts at 3000' below and is ~300 feet tall, and one of my Master ones appears to be ~500 feet tall, starting at ~3264, and I think I got shafted by my Expert World, making my Wall Of Flesh kill a lot harder due to less freedom...
So, now I'm wondering, if my first Wall kill was in one of the hardest a.k.a shortest Underworlds, what's the easiest, a.k.a tallest?
