Meanwhile, with rainbow..... lost Sol but all 3 attempts of stage 4 were fairly smooth, 1 attempt was close though. You might have been able to start clearing stage 4 now if you kept Mastema's staff, but it's a defender and those weapons are always useless right? Guess not.
My water team was also able to clear all 3 stage 4 attempts without an elixir. And the best part, the only heals my water team had was Joan's regen. Too bad I didn't record those water team runs though. I'm very confident the rest of my teams can do the same, especially considering water is one of my weakest elements.
