@@jorgeluishurtartegalvan747 Haha all over F21 it gets pretty hard f2p but here what i used: 1st Bttale APHO Beta, SF Rose, Yellow Cid SS+, Iris Tank 2nd Battle School Eta, young blue Beta SS+, Bespi, Masked Claire, school Delta 3rd Battle Masked Nu, Summer Alpha, SF Shadow, Young Epsilon SS+, young blue Delta SS+ Some tipps i can give you: First Boss: - Nothing that special besides a lot of HP and some heavy attacks - Annerose helps to get good buffs to deal enough dmg. You may need to reset a view time to get good EVA RNG Second Boss: - You need to cancel the buffs from the boss (Bepsi) - Big HP Third Boss: - You also need buff cancel or else the enemy gets a lot Reduce DMG Received buffs (Masked Nu) - The HP of the Boss compare to the others is not that much - The Boss lowers your ACC... So summer Alpha helps a lot here For higher floors we need better SS+ weapons to beat them with only free units. But i will make videos from time to time if a floor gets beatable. I also upload more difficult floors that i beated with my teams so stay tuned ✌🏻
