In Shadowbringers, healing is done in three ways. First and foremost you get a regeneration effect that lasts for 5 minutes from the Life skill. This regenerates your HP to full as well as replenishes MP at an even rate. Along with this there are certain items called Healing Items that can be found throughout the game which give a 100% recovery of both stats and also remove all debuffs on their own, though they cannot be used more than 50 times before becoming useless after use. Finally theres potions which have no real limit to how many you can carry but must be consumed one by one then reapplied each time theyre taken off cooldowns or worn out completely
