The Retainer service is an optional service that lets you purchase up to six extra slots for hiring retainers. These retainer slots apply to all characters on the affected service account. To start hiring additional retainers for an extra charge, please log into the Mog Station (https://sqex.to/Msp), select your service account, click on "Additional Paid Options" from the left the menu on the left hand side of the website, and choose “Retainer Service." Please note, as the Retainer Service is subscription-based, it cannot be paid for with Game Time Cards.
