Use highly different sets of movements, based on the weapons you have equipped, to change combinations, unlock new attacks through upgrades, and add job specializations that will help you expand Jack's and his companions' skill sets.
As with classic Final Fantasy games, HP, MP, and filters must be carefully balanced with the ability of limited use, soul shield, to reduce incoming damage - all in real time. In a new variation, if you rest at save points, enemies also respawn for easy grinding and risk-reward balancing.
