Guild Wars 2

I got lucky and found an ‘get 1 acending weapon with knight stats’ box.

I’m not sure how to use it best:

Staff for elementalist (WvW)
Hammer for guardien (PUG dungeon/hammerbuild)
Axe for warrior (PUG dungeon)
Sword for Mesmer (PUP dungeon)
or some other weapon for som other class? (I have level 80 everything, most farming in orr).

I’m not sure where to put a knight weapon and get the most out of it.
The rest of the (main) weapons will be crafted bezerker over time.

Hammer guard..

Knight stats? Hammer guardian.
