now, as far as i can tell, the only way to recharge this number is to use "healing spots" around the world, but they're very far apart. after a battle, your HP and MP is recharged, but if your VP drops to zero you start every battle with 1 HP and MP, and you can't use potions and stuff outside of the battle.
it might seem confusing, but it makes sense if you play the game. my question is, for anyone who has, am i missing something?! is there another way to recharge your VP? it's really frustrating me.
