Greatly improves the recharge rate of your Solar abilities while Hammer of Sol is charged.
While your Solar Super is charged, ability final blows cure you and give stacks of Sunfire Furnace.
While Sunfire Furnace is active, grenade and Shieldburst final blows trigger an ignition. Each stack increases grenade regeneration, class ability regeneration, and Super damage. Upon exiting your Super, all stacks are converted into Super energy.
