The Kanohi Ovaki is the Great Mask of Adaption. The Ovaki allows it's user to adapt to any defeat, meaning they can't be beaten the same way twice. However, should the mask be removed, it will "reset" itself in the sense that the defeats the mask's wearer has had can occur again. Also, the Ovaki's power has no effect on tactics that simply trap or slow down the Kanohi's bearer. Kanohi Ovaki can be made from Regeneration, Reconstruction at Random, and Enlarge Kanoka.
