The Mask of Insomnia is a Kanohi that can cause a being to become tired, and can make weaker targets (or injured targets) fall asleep. It can make any Rahi, of any size, fall asleep.



  • Unlike the Mask of Slumber, the affected target will wake up, and they are not induced into a temporary coma.
  • Although Feyran's mask has an eye piece added to the side, all others do not have that added on it. As such, it looks like the Taiku.
