Kiril

The Kiril is the Kanohi Mask of Regeneration. So far, only the Noble Kiril has been seen in the Bionicle universe. It can fix broken inanimate objects, but not wounds or anything organic. It is also limited. The only wearer of the Kiril so far has been Turaga Dume.

It is possible the Great Kiril can heal wounds and do it to a massive extent, but this is only speculation.
