At the start of the first battle round, select one of the following Benedictions of the Omnissiah to be active for Cult Mechanicus units from your army until the end of the battle:

Each time a CULT MECHANICUS model from your army makes a ranged attack that targets a unit within half range, improve the Armour Penetration characteristic of that attack by 1.

Each time a CULT MECHANICUS unit from your army is selected to fight, if that unit made a Charge move this turn, until the end of the phase, add 1 to the Strength and Attacks characteristics of melee weapons equipped by models in that unit.
