There is a goblin in certain areas such as L. Jeuno, you earn points daily or by trading items I believe. You can then spend the points on Random items..

You have to pick a number between 1-5 and it takes that amount of points from you x10 so 1 = 10, 5 = 50 and so on, you are then given an annoyingly long CS and an item.

Items are random. From no.5, I got (max 1): Dragon Steak, Nebimonite, Logs and an X-Potion.
