The Strongest for Cooperative Boss Challenge: The Ikusei Maguro Theory

Ikusei Maguro's Skills: - Adjacent Enhance (9-10x) - Blue Trace Clear (10-12 pieces) - Allows the next character to use their skill again. This synergizes extremely well with the Cooperative Boss Challenge. First, the Cooperative Boss Challenge requires you to fight a boss with multiple life points. However, the time limit is only 2 turns. You can only deplete one life point per ally attack, so the number of actions is crucial, whether it's through skill bursts (no turn cost) or trace clears (turn cost). Although all allies' skills are usable at the start of the Cooperative Boss Challenge, Ikusei Maguro can: - Perform a pseudo skill burst via trace clears (no turn cost). - Allow skill burst units to act twice. - Greatly enhance skill burst units or attack units. Therefore, depending on the power of your deck's enhancement units, it's ideally possible to deplete 4 of the boss's hearts in one turn: Enhance x 4 -> Maguro Trace Clear (♥ x 1) -> Skill Burst (♥ x 2) -> Trace Clear (♥ x 1) (This becomes harder as the boss's heart HP increases).
