A.D.B.P. Enhancer is a Medal in Bug Fables. It grants Vi's "tossing skills" 1 additional hit, but increases their TP cost by 1.
It can be viewed as a direct upgrade to Vi's Tornado Toss, Hurricane Toss, Needle Toss, and Needle Pincer skills, allowing them to hit 1 more time for just 1 extra TP. It should be equipped if these skills are used often, in order to take advantage of any leftover TP.
