Aside from being overly large, the Zu is not much of a threat to most experienced players, but it is known for two things: a large amount of HP and elemental attacks. Due to the fact that it is a flying monster, the player should use Gravity to disable this monster temporarily.
[view·edit·purge]Zu means "fire" in the Sumerian language. Anzû, before misread as Zû, is a lesser divinity or monster in several Mesopotamian religions. He was conceived by the pure waters of the Apsu and the wide Earth, or as son of Siris. Anzû was seen as a massive bird who can breathe fire and water, although Anzû is alternately seen as a lion-headed eagle (like a reverse griffin).
