Bang and Bomb can perform an attack together called
Whirlwind Water Stream Roaring Aura Sky Ripping Fist
is this attack just supposed to be a combination of Whirlwind Iron Cutting Fist and Water Stream Rock Smashing Fist power, or is it supposed to multiply them? Why their single attacks dont exhaust them, but the combined one does and can be used only once per battle? Is it because it demands more power?
