## Description

The Fierce Phobia is a combination of Hammer’s Semtex Hybrid coverstock and Phobia core. It is designed to create an aggressive mid-lane and backend reaction. Fierce Phobia not only complements the pearl Phobia but the rest of the Dark Legend and Black Widow line as well. This ball strikes so much, it’s scary.
With Hammer’s patent-pending carbon fiber infused outer core, the Fierce Phobia carries Hammer’s industry leading three year warranty.
