Medicinal Mastermind (3.5e Feat)
From D&D Wiki
Medicinal Mastermind [Skill]
You are so practiced in the ways of medicine, you can offer immediate recovery to small injuries.
Prerequisite: Heal, 7 ranks, Self Sufficient
Benefit: You may attempt a heal check at varrying difficulty, depending on how much you attempt to heal. Roll any standard dice for the amount you will heal to the target. Add the maximum roll of that dice to 10, this determines the DC of the heal check you must make. For instance, if you heal 1d6 to a target, you must succeed a DC 16 (10+6) check. If you fail this check, deal half of the half of the health you would have otherwise restored to your target.
Normal: Heal provides no immediate recovery.
