During the battle the Agents can spend Glory to call for support from friendly forces on the battlefield. The support available varies per mission, and is listed in the equipment section for the mission.
Calling for support is a full Combat Action. Once called support may take some time to arrive. Players should be the ones to roll the dice for support actions, but these rolls do not generate Wrath, Glory, or Ruin. Use the profile for Scions (Wrath & Glory, page 103) for any supporting troops who arrive.
Note that the party has the support of 30 Tempestus Scions. If all are lost they can no longer call on them for support.
The Agents are backed up by 30 scions led by Captain Reeves. Allow whichever PC has taken command to make a DN 4 Leadership (Wil) Test on their Turn. On a success, the Scions destroy a Mob of heretics. Each Shift destroys an additional Mob. Each dice that does not score an Icon represents one Scion either killed or seriously injured (and out of action).
On a Critical Hit, ignore any casualties caused by the roll.
On a Complication, five Scions are lost.
After the fight, one character can attempt a DN 3 Medicae (Int) Test. A success restores one Scion to the fight, with each Shift restoring one more.
