An Act of Faith can be attempted immediately before a Sisters of Battle unit acts during a phase; e.g. immediately before the unit moves in the Movement phase, shoots (or runs) in the Shooting phase, or strikes blows in the Assault phase. To attempt an Act of Faith, select the unit and reduce your Faith Point total by 1, then roll a D6 and add the following:




+1 if the unit is led by at least one of the following: Sister Superior, Retributor Superior, Dominion Superior, Seraphim Superior, Celestian Superior or Mistress of Repentance. 




+1 if the unit has been joined by at least one of the following independent characters: Canoness, Ecclesiarchal Confessor, Saint Celestine, Uriah Jacobus or Arch-Confessor Kyrinov. 




+1 if the unit has taken at least 1 casualty. 




Note that all modifiers are cumulative. If the total is less than 5, then the Act of Faith fails. The Faith Point is lost and nothing happens. If the total is equal to or greater than 5, the Act of Faith is successful. The unit immediately gains a bonus and/or special rules until the end of the phase. The nature of the bonus depends upon the unit that is using the Act of Faith, as detailed later.




Independent characters that have the Acts of Faith rule benefit from any bonuses received by the unit they are with when an Act of Faith is used. Similarly, units that have the Acts of Faith rule benefit from any bonuses received by an independent character that has joined the unit when an Act of Faith is used. 
If both a unit and an independent character have an Act of Faith that takes effect in the same phase, you must attempt each Act of Faith separately. 




For example, if a Canoness joins a unit of Celestians then you would require two Faith Points (and two Acts of Faith) to use both the Passion and the Hand of the Emperor Acts of Faith in the Assault phase.

Profiles:

Act of Faith
Light of the Emperor: This Act of Faith can be used in the Movement phase, the Shooting phase or the Assault phase. If used in the Movement phase when the Battle Sisters squad are falling back, the unit immediately regroups, despite any normal restrictions. If used in the Shooting or Assault phase, the unit rerolls any failed To Hit rolls of a 1 until the end of that phase. Note that the same squad can use Light of the Emperor in two or more phases if you choose, but a separate Faith Point and Act of Faith test are required in each phase.
