The intermediate Sage vocation in Dragon Quest VII: Fragments of the Forgotten Past for the Nintendo 3DS builds up powerful spellcasters who specialize in healing and revival, but can also hold their own in a fight with the help of some devastating attack magic. Their bodies are rather frail, so their buffing expertise comes in handy.
How to become a Sage: Visit Alltrades Abbey and make the switch after mastering the Priest and Mage vocations. Priests care for their allies' well-being with the aid of healing magic and buffs, whereas the Mage specializes in magical attacks that target single enemies, enemy groups, and all the enemies on a field.
Stat boosts and detriments: Sages take a hit to their Strength, Resilience, and Max HP, but enjoy nice boosts to their Wisdom and Max MP.
