Hau

The Hau is the Kanohi Mask of Shielding. It allows its user to protect themselves from any physical attack that they are aware of by throwing up a force shield. The only difference between the Great and Noble versions is that the Great version forms a stronger and longer-lasting shield than the Noble one.
