Sparkling Pink Rejuvenation is a spell is a spell that restores a single alliied target's HP and removes the 
Poisoned and 
Stunned status effects.
The amount healed by this spell is the same as Healing Light (assuming the same MAT between Eric(a) and Natalie). It is particularly useful for any of the fights where Eric(a) is alone, or if the party is being overwhelmed and somebody needs a spot heal while Natalie is doing party healing with Life's Radiance. It may also be helpful if Natalie is stunned, or if someone is poisoned and you really need to remove it mid-fight.
