''if'' sold at shyla, make it cost red coins, since those are a better currency imo at the moment than gold is.
If not sold at shyla, can do some funny stuff with the introduction of them to promote dead content and life skills and such.
if it is ever introduced, i agree with the red coins being the only way to purchase such item.
the enchanting or repairing process overtime is a very taxing and montonous grind if rng doesn't favor you.
imo, the purchase should be a ridiculously amount of red coins as well.
