1. Why do players post items in auction for absurd prices (like a lock for 1m)? I guess the thought is that someone will buy it by mistake. Has anyone succeeded at doing this? Or do they just like to throw away gold.

2. Does the nox of multiple rogues stack? My assumption is that it does.

3. Does charging traps do anything?

There are a lot more. I just can't think of them now.
