Boon of Monk's Frenzy

If you already have access to the monk feat Flurry of Blows you gain the ability to make an overwhelming number of attacks against a group of enemies. When you use your Flurry of Blows, you can make up to three additional attacks with it (up to a total of five Flurry of Blows attacks), provided that each Flurry of Blows attack targets a different creature this turn.
