Upon selecting either a piece of gear or materia in the inventory interface, you will be presented with the option to request this service. Making the request incurs a fee commensurate with the required level of the item to which materia will be melded, payable in gil to the player who accepts the request.
* In addition to the abovementioned fee, players must also provide a suitable catalyst.
* This method allows only the melding of the first piece of materia to any given item.
* Only players who possess a materia assimilator can make a melding request.
