RIFT platinum is the in-game currency for the free-to-play MMORPG RIFT. Platinum can be obtained through a number of ways and has many uses, from buying supplies for your character to trading with other players.
Platinum can be gained in large quantities through a means known as "farming." There are many methods for farming platinum, but some of the most common involve using the in-game auction house to list items that other players can purchase. Once a player has enough platinum, he can purchase powerful weapons and armors, as well as REX. REX is short for RIFT Exchange. It is a currency that free players can use to purchase some of the benefits that paid subscription players receive.
