Cash (can also be called Cash Points) is basically a second type of currency in Grand Chase that you obtain buy purchasing them with real money. Cash can be used to buy weapons, equipments that the players can wear, pets, pet attacks and more in the shop. It should be noted that Cash armor and weapons are somewhat stronger than GP armor and weapons of the same level.
Missions bought with cash are noticeably easier than with GP. Second job missions bought with cash, for example, require you to collect 10 fragments and 1 seal, instead of collecting 300 fragments and 10 seals. Character cash missions may only require a Crystal or Gem.
The cost in Grandchase (GCNA) is 1 American dollar for 1000 cash.
