Guild Wars 2

I used Gift of Quartz and nothing happened. I dont know that it is supposed to do, but I did not get anything….

Check your home instance, there should be a quartz “ore” there.

i have 8 characters, what home instance? and how does it look like?
Also, what is a home instance? is it a city or the maps where the we do the hearth missions?

It has the ore icon on the map.
