Is it worth recruiting Hyperion and getting him to 6 star just to move on to Stage 10 Corvus? (I’m a causal WBU player who intends to move up in the challenge)
I had the same decision to make and used a bunch of RUTs to get him to 6*. I figure that they'll have to deliver the rework at some point. But really depends on how much spare RUTs you've got laying around.
If you can afford the 450 crystals to skip it, I would recommend that instead
