The Azrael is an enemy from Final Fantasy III fought in the Ancient Ruins. Like most enemies in the Ancient Ruins, it splits into two when attacked with a weapon that is not a Dark Sword or if the monster does not get inflicted with Paralysis. It is therefore recommended to take a couple Ancient Swords that can be bought in the ruins along to fight these enemies. They are not overly difficult unless the player forces them to split too much.
Azrael is the name of the Angel of Death in Islam. Azra'il (عزرائيل) or Azra'eil (عزرایل) is the arabic etymology.
