?-4 is an infuriating RNG fest, but it didn't bother me, since it drops Life Crystals, otherwise obtained at a rate of 4 per day, so I'd be farming it anyways. I just use default setup and on the 6th try got the 3-medal. W/E, I'm going to keep farming it lol. Got 4 Rainbows I'd like to skill up lol, though I doubt I'll get more than 1 Skillbloom, 2 by the end of the 2nd phase, unless I go hardcore whale on the stamina refills.
