I also enjoying utilizing throwing knives. It's kind of a show-off thing but sometimes just beating someone isn't enough and you really want to hammer home that not only have you beaten them, but you're also a lot more graceful than they are.
There was a hotel called the Overlook here about a week and a half ago. It had some kind of magical draw that tempted people to enter it, and then it acted like a complete dick and made everyone relive their worst fears. Luckily, we vanquished that fucker and it went away. Such hostiles are not common here, but common enough that I would keep up with my knife-throwing just in case.
