This guy, if you're very careful and don't accidentally kill him instantly, will spew a Silence poison on you:
There's a couple animations at the end, like the crumbling of the totems and the closure of the weird portal in the background, that were pretty nice touches. Though so little new content is released in comparison to what we actually spend our time doing - 45 minutes of logging in characters to get Shadowy Supplier and Hireling mails, doing writs, grinding old content for gear, etc - that you have to savor the innovations that get added when they arrive. I wouldn't mind hitting someone with a silence poison, but I'll have to settle for my Cowardice poison for the moment
