The Sage (セージ) is the usual promotion of the Mage class in several Fire Emblem titles, and also the promotion of Shamans and Bards in Fire Emblem: Genealogy of the Holy War and Fire Emblem: Thracia 776, as well as an optional promotion of Monks and the Priests in Fire Emblem: The Sacred Stones.
It is interesting to note that in Fire Emblem: Path of Radiance, mages had the choice of either knives or staves upon promotion, with all Pre-Promoted sages having chosen the former. This marks the second occurrence of a magic-wielding class gaining a non-magical weapon upon promotion (the first being the Mage Knight of FE4, using swords), though the latter option is ostensibly more useful, in that it adds healing powers that draw upon the unit's magical power, whereas the former are not especially useful in the hands of sages, who will most often have low strength growths. Although it does offer a chance for a mage to attack units with high resistance with something other than magic.
In Shadow Dragon and Shin Monshō no Nazo WiFi battles, Sages are used mainly for their utility value. No sage is able to kill a combat unit one-on-one, such they are mostly used for their staves. In particular, staves like Fortify and Warp provide a team with a large tactical advantage.
The actual value of having a sage on a squad is debatable. A sage on a team introduces a weakness in overall composition in that the sage can be killed in a one-on-one encounter, but cannot kill others in one-on-one combat. Long range tomes like Swarm give the sage good finishing moves, and high versatility. The predominant reason sages appear on a squad is because they do not drain stat increasing items needed to make a squad of five powerful units. Normally, a team of five combat units would need to spread the boosts thinner and would have little need for magic boosts. However, a team of four combat units and a sage will be able to distribute their limited boosts to the combat units by especially focusing magical growths onto the stage.
Additionally, the map can affect how useful a sage may be. Map 6 in particular places a great emphasis on sages where most other maps do not.
In Fire Emblem: Radiant Dawn, the Sage class is split into five different classes. Fire Sages, Wind Sages, and Thunder Sages are able to use all three forms of anima magic, though their promoted forms are only able to acquire a ranking of SS in mastery with their preferred form of magic.
