first try after trying to understand the 2nd team mechanics in 3rd floor, i did some blunder in the video but as long i get 3 star im not complaining.
2nd team strats:
ignore the toughness bar on each enemy, and always keep ur eyes on the enemy's Tally Point(the number displayed beside their toughness bar), if it reached the max tally point, they will automatically turn to weakness break state (each enemy's has their own max tally point), and everytime u break one of them, the actual toughness bar (in the top middle screen) will get reduced depending on which enemy u break.
