Alright, so i'm thinking how much custom plugin like this would cost: Alright, so gems. You get them from mining (able to change chance of getting gems in config) and are able to use they to buy items. (can be edited in the config.). /Gems shows how many gems you have. /Gems (player) shows how many gems another player has. /Gems Help shows the user how to use gems (in text). And /gems use opens up a GUI that a player can use to buy an item that costs gems. (Prices and items can be changed in the config). How much would this cost? thanks!
