The Kanohi Taiku is the Mask of Poison. It allows the user to poison an opponent's body, greatly weakening them. The power of this mask can eventually kill a foe should it remain active for an extended period of time. While a powerful mask, the Taiku cannot increase any pre-existing powers of poison its user may possess. It can, however, poison a foe from a considerable distance; unlike the poison powers of Makuta or Rahkshi, which require physical contact. Like most masks, the Taiku requires constant concentration in order to be used effectively.
