The Mindflayer, also known as the Sorcerer and the Mind Flare in the NES and PlayStation ports respectively, is an enemy in the original Final Fantasy.
They appear in several dungeons in the game, such as Flying Fortress, the Cavern of Ice, and the Chaos Shrine. They are dangerous foes, as they have some potent special attacks. Its physical attack, while doing only one point of damage, may cause Instant Death to a sole party member. They also have high Magic Defense, making them hard to hit with magic, and to make things worse, they do not have any weaknesses. Physical attacks are the way to go, but their Mind Blast ability can target the party's physical fighters, which in turn can hinder the player's fleeing abilities.
