I'm assuming it's going to be a struggle just to beat the later stages let alone 3s, so I'll give each a go or 2 then move on. I didn't finish NM campaign until the mission (Marius or ramantu? ) and that was a little bit easier. I think getting Marius was the only time I really rushed to getting a "one-time" reward. I thought it was stupid at the time, never thought he was going to be THAT good. 😆 in retrospective no regrets on that one. But that was easy, just tons of gems and masterful planning :)
Makes sense. Marius is literally game changing everywhere, Polara I suspect will just be a good arena nuker.
