The reds in question are Azlar 2^60, Natalya 2^60, Scarlet 3^60 and Colen 3^40.
I have mats for one ascension.
My thought was Nat and Scarlet perform well at this level, but Azlar could put the power boost to good (better?) use. Then I checked Colen’s numbers, and he has better power than Azlar as he progresses.
Is Colen my best bet here?
