With slightly below 50k total power, it was sufficient for me to run Metis+Sol combo (Metis gives immunity to Sol, Sol can cleanse). I did run a Behemoth friend and I did use her once to avoid getting nuked. But the previously linked strategy assumes tanking one nuke, so maybe it would be sufficient to have Fluffy friend and tank 1 hit... Not sure yet how to approach 3xR next week, as having Metis + Sol + R might not be enough damage.
