I'm guessing "PK them" is either kick seven bells out of them or make them join your party?

That's what the outposts are for really. To get people to join your party. And if you want to kick seven bells out of them, then just have a bash in the PvP arenas.

I'm gonna start a new character today. I thought maybe N/R, but we'll see. I'm doing it with a friend - we're gonna both become the same build, and bash our way through the missions, see how far we can get in a day.
