Favorite One is a Medal in Bug Fables. It decreases an ally's defense by 1, but when the ally takes damage, all other allies gain 1 charge.
Its effect is similar to what Team Mothiva and Team Maki have, and is quite powerful. The defense reduction can be nullified by using a defense-increasing medal or item. It should be noted that only 1 charge can be gained per turn, regardless of how many times the ally with the medal gets hit.
How to Acquire
There is 1 Favorite One medal available. It can be found during Chapter 2 at the earliest, after the Golden Festival ends, by completing the Dropped my Hat! quest.
