Scimitar of Twilight

The Twilight Sword is a mysterious blade used by Zant to resurrect Stallord in Twilight Princess. When Zant confronted Link in Arbiter's Grounds, he placed the sword in the head of the fallen beast, awakening the once dead creature, and beginning the fourth boss battle. It is unclear if the Twilight Sword has any other powers, as it is not used or seen for the remainder of the game. It is possible that it gave Stallord many of the powers he has such as calling upon Staltroops and flying after losing his body. The sword is also Stallord's Critical Point in the second half of the battle, after destroying his spine.
