Guild Wars 2

hi ,question- how do you get glider wings that work in www.I asked question during www zerg and no one answered.I did quick check in store but I did not see glider wings
on sale at gw2 store.How do you acquire these glider wings.i feel real foolish when a www zerg jumps off a cliff and I drop like a rock when they glide.
Many Thanks!!

You need to spend World Ability Points (which you get from gaining rank i WvW) in the “War Gliding” track. To be able to do that, you need to have Heart of Thorns.
The first rank (allowing you to glide) takes 3 points.
