Dominions 5 Wiki

Sacred units can be blessed by priests or the presence of a pretender during a battle in their own dominion. This causes the units to gain +1 morale, as well as all the effects of the pretender's bless that were chosen at the beginning of the game, plus additional effects gained from certain claimed thrones. They also have a halved upkeep cost compared to a non-sacred unit of the same gold cost.

Prophets are always blessed, even on the strategic map. Pretenders and disciples are always blessed in friendly dominion. Additionally, the Shroud of the Battle Saint allows a non-sacred commander to become permanently blessed.

When blessed, the sacred icon changes to a form with lit candles.
