Physician A5E
When you use a healer’s satchel to stabilize a dying creature, it regains a number of hit points equal to your Wisdom modifier.
You can spend an action and one use of a healer’s satchel to tend to a creature. The creature regains 1d6 + 4 hit points, plus one hit point for each of its hit dice. The creature can’t regain hit points from this feat again until it finishes a rest.
