The Agaliarept, also known as the Agaria, is an enemy in Final Fantasy III fought in the Cave of Tides. It is the strongest enemy in the cave, and should be dealt with quickly to avoid taking too much damage. Lightning-elemental attacks are the best way of taking them down, so mages should use Thunder from the Light Staff, while having any Scholars attack with the Light Book.
Agaliarept is a theological demon from various texts, such as the Grimoirium Verum and the Grand Grimoire. It is stated to have the power to uncover secrets and reveal mysteries.
