It seems I am not the only one struggling. This revival has drained the life blood out of me and I just got Dorania. I need another 630 crystals for Fleur and Echidna and I still have to focus on speed leveling other units to be able to do the last map. Speaking of which, I am not at all interested in 3 staring it. All I am interested in is to get all the crystals and surviving the map. I have no qualms with having two or even one star but all the videos focus on having a perfect run. Does anyone have advice on only surviving and getting the crystals?
