Spell

Fortitude

Provides your target with mystic fortitude, increasing their hit points and armor class for 2 hour(s) 24.0 mins. This spell trades the higher AC and HP of Heroism for a longer total duration. However, due to the lack of a group version of this spell (such as Heroic Bond for Heroism), and the lower total stats, Clerics tend to use Heroism and Heroic Bond instead, until getting Aegolism (which lasts roughly as long as Fortitude while keeping the stats of Heroic Bond).
