Brandishes an Exotic Shield

Anyone can use a shield. But few can project a protective force field that crackles with otherworldly energy. Maybe your ability comes from a childhood encounter with a strange machine or a metallic nodule that protrudes above your flesh along your spine, or perhaps it is something that people in your family are capable of once every few generations. You use your force field to not only protect yourself, but to aggressively bash those who would do you harm. At first, you can create only a small protective plane. But as your skills improve, you can learn to throw it at foes and have it rebound, heal allies, and release an explosion of destructive energy each time it strikes home.

Glaives and Delves are most likely to choose this focus.
