Gonshi

Gonshi Mushrooms: Eating a Gonshi mushroom before or during combat will give a party member a burst of magical dexterity. When next the member acts, he or she gains a bonus to dextarity.
Property:  As a swift action, you can eat a gonshi mushroom.  Gain a +2 to your next dextarity based attack roll.  If no attacks are made within 24 hours of using a mirget, the bonus fades away.
