"Jaller looked up to see that she was facing away from Matoro, apparently having a conversation with the empty air. He wondered for a moment if Hahli had gone crazy."
— Narration, BIONICLE Legends 3: Power Play
Mask of Detection
Power(s)Detects hidden beings and the Ignika
Notable Wearer(s)Hahli (fomerly)

The Kanohi Elda was the Mask of Detection. It granted its user the ability to sense the presence of any nearby hidden beings, such as a Huna or Iden-bearer, and allowed them to track the Kanohi Ignika through increasingly strong headaches. For this reason the Kanohi Elda was a somewhat rare Kanohi because its primary purpose was to locate the Ignika.

Kanohi Elda were always on at a low level.

The only difference between the Great and Noble Elda was that the Noble only allowed the user to see hidden beings.

Example Usage

Great: Hahli's Elda let her see and hear Matoro's spirit in BIONICLE Legends 3: Power Play. She also tracked the Ignika's location within the same book.
