The Rua Nuva was the Kanohi Nuva Mask of Wisdom. It gave its user and those nearby the enhanced powers of X-Ray Vision, Levitation, and Water Breathing. The powers could be activated individually or separately by the user(s). Rua Nuva can be made by dipping destined Rua in Energized Protodermis or by merging Miru Nuva, Kaukau Nuva, and Akaku Nuva together. Only Toa Nuva can activate this mask.
