Skill combinations are like opening blind boxes. "Venom Ray + Barrage Shot" can trigger "Full Screen Poison Domain". However, the "Frost Mech" skill was used incorrectly last time, freezing the movement system of the party. Just when it was about to be hit by the BOSS "Thousand Machines", the ice layer suddenly reflected the tail spike attack, activating the "Reflective Counterattack" buff, and countered the first phase BOSS to clear the level.
