Nocturn

The Nocturn is a ghost-like enemy found in.

Characteristics
The enemy is encountered in the Tower of Spirits on the third and sixth visits. They will hover out of reach in the darkness, but when they suddenly get exposed to the light, they fall to the ground, weakened. This can easily be done by lighting up the torches around with the boomerang or by using Princess Zelda to possess a Torch Phantom to move around with a light. Once this is done, Princess Zelda or Link can attack the Nocturn. After obtaining a Bow of Light, Link can shoot a Nocturn in its back with a fully charged Light Arrow.

Nomenclature
Its name is derived from the word "nocturnal", referring to the fact that they live in the dark and resent the light.
