Calix

"Oh, how did you learn to do that move?" "It's the mask--lets me do things others can't."

- Hakann and Jaller, Comic 3: Showdown

The Kanohi Calix was the Mask of Fate. It gave its user the power to perform acts at the absolute top of their natural physical abilities, better than almost any unenhanced member of their species. This let them pull off feats others considered impossible, such as incredible leaps or dodges. While it did not allow the user to do something impossible, it did alter probability to aid them.

Example Usage
In BIONICLE Legends 3: Power Play, Jaller used his Calix to mostly dodge a combined blast of power from Hakann and Thok.
