How to unlock the The Faithful achievement in Warhammer Age of Sigmar: Storm Ground - Definitive Guide
Divine acts are found as loot in the campaign. They are sort of like spells. You'll equip them just let you equip a unit. Then, in the next fight, once you've earned enough of the purple gems in the upper left, cast your divine act to earn the achievement.
