The Kanohi Kiril was the Mask of Regeneration. It gave its user the power to repair damage to inorganic objects within their range of vision. The only difference between the Great and Noble Kirils was that the amount the Noble Kiril could regrow was smaller. Neither versions of the Kiril could heal organic damage; only the Great Kiril could regenerate Protosteel.
