"One you have completed the quest “Mmmmmm, Soulglazed Relics,” you will be able to alter the materia-enhanced properties of your relic weapon novus or relic weapon nexus. Prepare a new sphere scroll of the correct type to receive the power of your chosen relic weapon, then use materia and alexandrite to redo the infusion process."

Is this for people who have made mistakes on their Novus and want to redo stats? Or do we all have to do another sphere scroll?
