The Staff of the Magi is treated as the ultimate staff, given its own license. However, at a glance of its stats in comparison to the Cloud Staff it may not appear so. In the original version the Staff of the Magi has 2 fewer Attack power but 1 greater Magick Power, but its increase potency in Holy is more useful than Cloud Staff's increase in Wind because Holy is a stronger spell.
In the Zodiac versions the Staff of the Magi is stronger, has an increase in Vitality (where Cloud Staff has an increase in Speed). Its potency in Holy is not as useful as in the original version because staves are used by Black Mages who cannot cast Holy (unless they have a second job with access to it in The Zodiac Age). The other difference of the weapons is Cloud Staff's additional potency of Water where the Staff of the Magi has an additional potency of Ice.
In the original version, its license costs 100 LP. In the Zodiac versions, its license costs 115 LP.
Staff of the Magi is a weapon.
Magi is also a term used since at least the 4th century BC to denote followers of Zoroaster, or rather, followers of what the Hellenistic world associated Zoroaster with, which was—in the main—the ability to read the stars, and manipulate the fate that the stars foretold.In Latin, Magi is plural of Magus, which means "wizard".
