When the user consumes a HP recovering or stat-boosting potion, healing and stat boost bonuses are increased by 50%. Learned by Apothecaries at level 1 or higher. A Merchant or Mechanist promoted from a Apothecary can also learn the skill.
In Warriors, the skill functions differently. Instead of increasing healing potency, it allows items such as vulneraries and concoctions to double as staves, healing adjacent allies in addition to the user.
