Let's begin. First, each attack slot has a number. They are 10, 20, 30, 40, 50. The highest is not 50, but a doubling! This is how a 50 number powered attack skill unleashes... the damage is still same.
Now let's see how a doubling works. It's all about luck... but it will dealt more damage than before!
At the end of a doubling attack, the attack with a doubling effect is called "Mega damage" and the attack damage is even more bigger than the 40 or 50!
