The Wight, also known as the Specter in the NES version, is an enemy in the original Final Fantasy. Wights is undead with the same weaknesses and resistances normal for undead enemies: Fire and the Dia spell. A Wight's attack can cause Paralysis, which can prove irritating if it affects a physical attacker.
Wight is fought in the Cavern of Earth and the Cavern of Ice, the latter being only in a small room, forcing the player to fight them automatically. It is not difficult to defeat them, but they sometimes come in large groups.
Wight refers to "a person of a specified kind, especially one regarded as unfortunate." In literary terms, it refers to "a spirit, ghost, or other supernatural being."
