Crafting dex/aura hunter amulet

Ok that's what we have on trade right now.
Amulet #1: cool amulet base, who even wants to waste efforts on this?
Amulet #2: GL annuling strength, also price is 18ex already
Amulet #3: GL annuling rarity, costs 20ex.
^ this totally nullifies your advice on "buying is cheaper. And yes, I asked how to do that bcz I didn't know how to do that, but find my way eventually. Don't need any kind of congratulations from you or anyone else :)
Also 20ex is already complete amulet, and 0cost base is same price. So at what point it is ever cheaper "to buy"? :))
