Make super from elite

hi guys...
how to upgrade equipment, example from refined to unique, or from unique to elite, or from elite to super.
i heard rumor that we can make it with db, but i dont know how????
can anyone explain it to me plzzzzzz
thx...

Yes. You use a dragon ball in Twin City, or the market NPC. I can't remember there names, but I am sure someone else will tell you on Conquer. But you do use a dragon ball.

It is not guaranteed though, if you do it the Twin City way, there is chance of failure. But the Market way is guaranteed. With no failure comes more dragon balls though.

Thank Tq for that.

the npc is artisan wind
