Dr. Lugae, also known as Dr.Lugae, or Lugaborg, is a storyline boss in Final Fantasy IV. It is the fiend form of Doctor Lugae. After the battle, Dr. Lugae's Key is obtained for use in the Tower of Babil to stop the cannons from destroying the dwarves.
Lugae counters attacks with Sleeping Gas. He uses Poison Gas to poison the entire party, as well as Flamethrower and Beam attacks, which do moderate damage. He uses Laser, which can do upwards of a thousand damage and can easily kill a party member. Lugae may also cast Restore on the party, removing Poison.
Rosa should heal after Sleeping Gas. Overall, besides Laser he is a simple and weak enemy to defeat.
