The Bandyborn

From publisher blurb: Drain to survive, drain to thrive, drain to win! A "banyborn" is a class that uses feral nature magic to drain foes and store that energy in gems that form on their skin. These predators can then "burn" that stored energy for fantastic effects! The book includes not only the bandyborn class but the "Bandy Priest" archetype which converts the bandyborn into a spell caster!
