Many front-line fighters can find themselves taking a massive, unlucky hit before their healer can get to them. This spell is a countermeasure. It surrounds the target with a purified aura of airborne blood, which seeps into them as soon as the next major wound opens up. Most of the damage from that wound is recovered over the next few seconds as the blood revives the target. Note that some attacks, such as harm spells, do not shed blood, and therefore do not trigger this spell. Spell percent affects how much of the damage is restored. Mastery speeds up the rate of recovery.
