Basic question :)

I havent played for 2 years so i dont really know what are those uber weapon or which mod make em so expensive. Can someone help me on that one?

It is the skin that makes them expensive not the mods.

all expensive guild wars items have such high prices because of the looks.

You can easely get a weapon with the exact same stats (but another skin) realy cheap.

its also because they're hard to get i.e eternal blades obi edges

And I'd like to know if someone with only GW Prophetie can get items from other expension?

yea you can but you'd have to have some1 bring em over to a proph place

I had scythes and spears drop for me before i bought NF, so thats a yes

but without buying end game greens no

To clarify, they don't DROP in the Prophecies campaign.

The only way to obtain skins from another campaign is to have someone trade it to you.
