Mirget

Mirget Leaves: Rubbing the leaves of a Mirget plant on a party member's arm magically increases his or her strength for the next swing of a sword or axe. If he or she connects, the damage will be great. But, if the opponent manages to dodge the swing, the Mirget was wasted. To avoid this disappointment, use Luffins along with Mirgets.
Property:  As an action, you can rub a mirget on your arm.  If your next attack hits it adds +2 to damage.  If no attacks are made within 24 hours of using a mirget, the bonus fades away.
