Ifrit (The After Years boss)

Ifrit is a boss from Final Fantasy IV: The After Years. In the first encounter with him, when fighting the Mysterious Girl during Edge's Tale, Ifrit is an unbeatable boss and must be escaped from. During the escape from the Tower of Babil, Ifrit will be in random encounters and the player will be forced to run from him.

Strategy
In the last Tale, Ifrit is yet again encounter as a random encounter that must be ran from in Eblan, and is then fought as a defeatable boss. However, it is advised to not kill Ifrit, as doing so will result in losing Ifrit for good. Instead, it is advised to whittle down his HP until he stops attacking, and cease all attacking to get Ifrit as a summon. Ice attacks such as Blizzara are recommended for this fight, as well as Arctic Wind. However, keep an eye on how much damage is being done so as to not kill him!
