Sanok

"The Toa of Stone shrugged and casually tossed the rock aside. Only Matoro noticed it hit another rock, ricochet, hit a second, and so on. [...] The boulder ricocheted one last time and slammed into Vezok's back."

- Narration, BIONICLE Legends 3: Power Play

The Kanohi Sanok was the Mask of Accuracy. It gave its user the power to use almost any inanimate object as a projectile weapon and hit almost any target he/she aimed for. A Sanok was always on at a low level.
