Campaign Operation Credits are used to sign up for Campaign Operations in each nation in Vana'diel's past.

• 1 op credit is required to activate an operation.
• 1 op credit is gained automatically every 24 Earth hours after completion of a previously used credit.
• Up to 7 op credits can be held at once, after which you cannot receive any more until an op credit has been used. It is possible to use a credit to begin a Campaign Op and still be able to store 7 credits in reserve.
• Op credits cannot be refunded. If you fail or cancel a mission, the op credit is lost.
