The player gains Soldier Points when defeating enemies, or by using the "Convert to SP" function in the Materia Fusion screen. These points are then used to spin the DMW, at the cost of 10 SP per each spin; as well as to create Materia through the Materia Fusion process.
If afflicted with the Curse status effect, the player will continue to accumulate SP, but will not be able to spin the DMW. In the event that the player has less than 10 SP left, the DMW will stop spinning. Materia Fusion will not take place if the player has insufficient SP.
