Have killed all ubers with it. Though wouldn't recommend doing anything but Maven, Exarch, Eater and Shaper.
Can actually freeze bosses.
Awakened Elemental Focus shows greater numbers on ninja but feels twice worse than inspiration on practice. No longer able to freeze which disables half of the Heatshiver.
