Guild Wars 2

As the title says. I’ve used all 7 skills repeatedly and my achievement is still stuck at 6/7.

Make sure you use some of them near other players. You can’t just ‘use’ them, they have to do something. I was at 6/7 too for a while then realised when i’d used the lightning strike before it wasn’t on anyone so didn’t count.

Ah I got it now, as you said my lightning strike wasn’t hitting anyone.
