Great Pohrai, Mask of Stone (axle)

The Kanohi Pohrai is the Elemental Mask of Stone, and as such allows its user Toa-level control over the element of Stone in its Great form, and Turaga-level control in it's Noble form. Like all Elemental Masks, the Kanohi Pohrai would not boost the elemental power of a Toa of Stone, but instead would act as a secondary source to draw power from when their own elemental energy runs dry.
