Guild Wars 2

So I have been hunting all over the place to see if someone has any information on how to obtain an Icy Dragon Sword or Corrupted Norn Sword. There seems to be a lot of people interested yet no one has said where to get them. drops? mystic forge? crafting? If you know anything please share.

They are a crafted item. Wep smiths get the formula from a npc that comes after the claw of jormag is defeated in frostgorge. You need a exotic 2 handed sword and a buch of other stuff roughly 10gold or more to make it
