There is a power that when you use it you can't be harmed... you gotta unlock it though, it's called maelstorm i think, and once you unlock it, you can use it by pressing Z+C+A+B and then you become surrounded by force, as long you have that on, no harm will come to you, and if any enemies come they'll get caught in the force then once you wanna kill them, swing the nunchuk and wii remote together to release the force explosion.
