Can someone explain the upcoming "SP" System?
I've read some skills use "SP."
Is it just stamina, or is it a separate bar?
Are the "SP" Skills more powerful than other ones?
SP is another bar, positioned below stamina bar. It doesn't regenerate automatically like stamina does. But by other special ways, I only know that Fiona can regenerate them by doing perfect guard and heavy stander.
And yes, these skills are really powerful / useful.
SP (Skill Point?) system is like... triggerable active skills that uses up a bar under your Stamina called the SP bar.
When you go buy skill books, you may noticed a skill book or two that has "SP" in its title. These skills are not triggered by Smash or some specific combo/situation, but by the "Z" (or whatever you assigned the SP activation) button.
