Amplified Healing

Amplified Healing is the first skill in 's Serenity skill branch, and the one she has unlocked by default. It makes healing arts 15% more effective on her. It does not affect other sources of healing, such as the Regenerate buff or healing gems.

Overview
Melia doesn't have a lot of HP to begin with, so she'll be low more often and thus need to be healed more to compensate. It's a cheap and rather easy link as well, and anyone benefits from it.
