(Teamwork)
Your link with your companion creature allows you to share with it any healing magic that's cast upon you.
Prerequisites
Ability to acquire an animal companion, eidolon, familiar, or special mount.
Benefit
When you and your companion creature have this feat, your companion creature is adjacent to you or sharing your square, and you receive the benefit of a healing spell (whether from yourself or another source), you can divide the hit points healed evenly between yourself and your companion creature.
