Bruh this is too hard I once got perfect health in phase 1 and literally get destroyed on the second phase when he gets big Man youre lucky he didnt spam the wing attack
There is also a glitch where the big chaos darkness instantly goes underwater after growing bigger, to perform the glitch u need to immediately press forward button and circle at the same time and press forward and square when cosmos is near chaos darkness.. After that, chaos darkness will goes underwater and get stuck until the timer ended.. This is the point where u need to charge the special move in order to end the mission, just keep charging until the special move is available and then use it, also, try to avoid chaos darkness's hand that is coming out of the water cuz it will always try to attack you
