Guild Wars 2

So let’s say I buy an amulet with Laurels. Does that amulet not give agony resistance as is? What I would then need to do is put in one of the fine infusions to get agony resistance? But then if I want to upgrade the amulet to an infused amulet it will destroy my fine infusion and give me 5 agony resistance from the amulet itself? Then if I put another fine infusion in I will get another 5 agony resistance?

Is this how it works? Correct me if I’m wrong!

Yes to every question that is how they work.
