Suggestion would be to make individual sales on gem boxes not a random , similar like we had in sales previously, certainty to get the right gem for players and after people could buy mermaid boxes to compound gems,
Prices I've put in just as close as I could to reflect prices in game prices are slightly cheaper also , Slycutter would put more accurate prices than I do as I'm playing in KR at the moment and spending less time in west,
