Redemptio sacrifices yourself in order to revive all party members near you. The skill will affect any party member within a 15 x 15 area around you, and they will all be revived with 50% HP. When successful, this skill reduces your HP and SP to 1, and you lose 1% of your Base EXP. For each person you revive with the skill however, the penalty is reduced by 0.2% exp. With 5 or more people, you do not suffer any EXP penalty. If you do not have enough EXP to cast this skill, it will fail.
