As the title says, I want to suggest adding “Upgrade Extractor” as random daily rewards, just like the bank, TP express and perfect salvage kits are right now.
For one, since the wardrobe system entered and we cannot use our transmutation stones anymore, Upgrade Extractors are the only way to remove runes that are on karma bought equipment now. They are not salvageable. I ran into this problem while purchasing a new aqua breather, gonna have to get a new rune or shell out 25g or more to get 250 gems for one because of that.
Second, it’s gem price is lower then other daily reward (BL salvage kit), so I don’t see any problem with it, and would be an useful alternative since the stones have been taken out.
