Aegis of Vitality

When cast, the Aegis of Vitality envelops the chosen ally in a shimmering, translucent barrier that absorbs incoming damage. Once the shield has absorbed a total of 20 points of damage (or until concentration is broken), it releases a warm glow that heals the ally for a portion of the damage absorbed, up to 10 points. If shield i broken before 20 points of damage due to concentration being broken, damage that has been taken heals for half (ex: hit for 6pts of damage, concentration broken, up to 3points of health restored.)
