Can you get another hero weapon?

[Relinquished Reality]

as the title says, is it possible to get another hero weapon? if so, how? I think its pretty lame if you can only have one chance to make your weapon customised to your liking. I have all of these guild seals left over and I think there should be something else to spend it on.

Unfortunately, you can't. However, what you can do is save in front of a specific chest, and if you don't get the morph you want after opening it, just dashboard and go back into the game to try again.
