Let's have fun with the mystic forge [skin spoiler]
My problem with the Forge is that it is VERY expensive to make anything, even if you know it, and the result is usually either trash or something that makes way less money than the investment you put into it. It’s just a big trash can you throw your money into.
But it can sometimes result in nice looking weapon. Hearth of the Mists greatsword, for example. Here are still unknown recipes which also might give beautiful looking weapons. Who knows? Someone can be first discoverer of something looking epicly. I’d try if I had more gold…
