Kiril

The Kanohi Kiril was the Mask of Regeneration. It granted its user the ability to repair synthetic targets, though the mask was limited as it could now influence organic objects.

The stength of a Kiril would be determined by the amount of damage that could be undone, with the Great Kiril being more powerful, being able to repair damage to Protosteel.

In Metru Nui, a Kiril would be made from Regeneration Kanoka.
