Guild Wars 2

I feel like I’m missing something really obvious.

I go to the mists and go to the dps testing waypoint. There’s a bunch of golems who have different levels of armor.

But I only have access to greatsword and scepter/torch as weapons. And I have pre-set armor and jewelry.

I want to try out iWarlock with a specific set of gear. How do I do this?

Go to the weapon smith vendor, on the ledge near the Tournament Master.
