Exalt

From IvaPedia

Syntax: cast 'exalt'

Use of this spell will toggle exalted status within a white mage. While a White Mage is Exalted, the legacy of the ancients courses through them, granting them the ability to cast several holy, yet very destructive, spells. The power, however, is too strong to focus into curative spells, and so the mage must cancel the status before casting heals.
