Gems

General
Gems can be collected via payment of robux or picking them up during a level. They can be given from killing enemies (if Gem Extractor is equipped), extra fairy bottles, ect. Gems are used to buy items ( the only exception is buying gems and Jade, the donation character ).

Shop
Gems can be bought at the shop. Buying gems does NOT give you the donation character. You must buy gems using robux.
