Well I got lucky (I think) with the Gachapons and got a Claymore with a gold colored blade. I believe I've heard that gold bladed weapons sell quite nicely, so I'm trying to figure out just how much is a reasonable price for selling this thing, both with and without proficiency.
I basically need to decide wether to use it myself, sell it as is, or try raising the proficiency and sell it then (which will be quite the investment in repair fees to keep it nice for sale.)
Any comments on the price of those gold and silver bars in my inventory would be nice to.
