Killing an Anet dev in PvP or WvW. It's called Conquer the Creator.
Edit: It doesn't give a reward of any kind, even though it's an achievement.
I love playing tagged up and seeing a whole zerg of players try to chase me down and murder me. I find it oddly wholesome.
There is also Carry the Creator (do a Raid with a Dev) Channel the Creator (do a Fractal with a dev) and Complement the Creator (do a strike with a dev.)
Oh I know, it's just the guild tag for the Arenanet guild that all devs are a part of, but afaik you only get the achievement if they're actively repping that guild
That is correct. When I do fractals, I don't put up the tag until the last boss is at like 5% health, and then I take it back down when the Transit Query comes up.
