Kefka's Tower Outside, Tower of Fanatics Top
Megalixir restores all HP and MP to all targets. They are incredibly valuable, particularly during the battle with Kefka as a response to Fallen One, but you'll only find two in the game. If you want more of them, you can attempt to Steal one from an EarthGuard before it dies of Seizure.
