Shielding

Shielding is when you hold the shield button down, and a bubble of energy surrounds you. Shielding can block all attacks except grabs and Final Smashes. A way to solve this problem is to sidestep before the enemy grabs you. While you shield, the bubble shrinks. Some Special Moves can be considered as shielding, such as Lloyd's Guardian, but they can't be broken. If you Shield too much, or if the opponent hits it too much you will be in a condition called Shield Broken.

Shield Broken
Shield Broken is when you Shield too much and it breaks. It will result that you get stunned. To get out of stunned condition, either wait (not recommended) or keep on tapping your control keys.
