STAMINA-POINTS represent your poise and strength to perform certain actions. When you evade or perform other moves, your STAMINA-POINTS go down. When at 0 SP, you can still do many actions, but at a disadvantage.
MOMENT OF SAFETY: At the start of evasion you have invulnerability briefly, so evade at just the right moment!
STABILITY: Take enough hits and you will flinch! If a hit is really big, you can even be knocked over.
The hidden STABILITY gauge is 25% of your total HP.
