This game is just stupid. If your f2p dont bother. You will spend all your gems just to maybe get 1 unit. the gatcha rate is abysmal. The devs dont care. And the lvl 100 bosses are all the same. You get them to 1/4 of their health and they just spam an aoe move that wipes your party. Every single one. Screw this game and don't support them.
