Guild Wars 2

How does one finish this one?
I’ve fought some of the champions in the pavilion but did not get any points …help?
Oh and don’t tell me to use the search function which has not worked for ages neither on firefox nor on opera or chrome…dunno why but I appologize if this has been asked. I’ve not found anything as of yet and I’ve searched by hand.

The Champions for that achievement are the ones you find in open world from the Balloon Pilots scattered around the maps.

Actually these champions are different. You find them in open world around those balloons. When you need to get balloon door opened, talk to its pilot and it will spawn one of these events – escort emissary or defeat the queen’s champion or lower aetherblade morale.
