Jagex has introduced the idea of PLEX to RuneScape in the form of bonds. Bonds, like PLEX, are tradeable items that are purchased from Jagex and can be traded to other players through the in-game auction house or face to face, to then be exchanged for in-game goodies. As a measure to stop gold farming, which Jagex believes involves 40-50% of the active player base each month, the bonds can then be redeemed by the buyer for membership (14 days), spins (8), or RuneCoins (160) for the cash shop. Not a great deal at face value, but the goal is that the buyer does not pay real money, and the person who did initially buy the bond is receiving gold from the buyer.
Bonds cost $5 USD.
