Zu follows a predictable four-stage attack pattern. On the first two turns, it uses a physical attack. On the third turn, Zu's wings will glow and on its next turn it will use Sonic Boom, which hits all party members. While it may look intimidating due to its size and powerful attacks, it is weak to Darkness.
When a Zu drops below one third of its maximum health, it will fall, landing on the ground. This renders it unable to use Sonic Boom. Flying Zus cannot be slain in one hit, unless from Zanmato or Doom. While airborne, it will always survive with 1 HP.
The equipment it can drop can have two to three slots with one to three abilities, with weapons containing either piercing, Str +5%, or Mag +5%, as well as Darktouch. The armor it drops has two to three slots, but with only one ability, Dark Ward. The forced encounter at the start of Bikanel always drops equipment, while other encountered Zu's have a 50% chance.
[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).
