Gotfret de Montbard

Before making a dice roll for a model or units from your army with the Acts of Faith ability, you can choose to use one or more of the dice from your Miracle dice pool instead. For each individual dice that is being rolled as part of the dice roll, you can select one Miracle dice from your Miracle dice pool to be substituted in place of that dice. The dice that it is being substituted for is not rolled, and instead the value of the chosen Miracle dice is used as if it had been rolled. Once all Miracle dice substitutuions have been made, remove the chosen Miracle dice from your Miracle dice pool, and roll any remaining, unsubstituted, dice that are a part of the dice roll. You can use Miracle dice to perform an Act of Faith for any of the following types of dice rolls:
Advance, Charge, Hit, Wound and Damage rolls; Saving throws; and Deny the Witch and Morale tests

Models in this unit have a 6+ Invulnerable Save (6++). Also, each model or unit with this ability can attempt to resist one a psychic power per Psychic phase by taking a Deny the Witch test, rolling one D6 instead of 2D6.
