I made a video of the the only element I can safely handle. Not sure if it's because my Water team is damn good, or because Fire is the easiest, or because my Water grid is in really good shape. Or because of a combination of all of the above.

I handle the pre-Rage boss really slowly, since that's the safest way. Andromeda generally heals more than what the boss dishes out, so I'm just chilling and waiting. With Water, I guess I could rush it too though. But why risk it?
