Luna blinked at Cadence a few times, "You're asking me? You're the expert on the Crystal Heart and its workings Cadence, so if you don't know, we certainly don't. I mean, the science is there. Use the gems as a focus much like the tower in the Empire, and reflect the Heart's energy back on itself so the runoff of energy is reduced, allowing you to use it for longer. I mean you'll still have to recharge it once a day, and will have to feed it to maintain a shield, but... yes, this should work. In theory."
