"It is not enough to serve the Emperor, or even to love Him. You must give to Him all that you had, all you have, and all you shall ever have. You must give yourself over utterly and entirely to His divine will and become a vessel of that will. Only then is your sacrifice fitting."
— From the Rule of the Sororitas

A new faction joins the war for Gladius Prime: the Adepta Sororitas, with eighteen new units and unique gameplay mechanics.
The Adepta Sororitas, also known as the Sisters of Battle, are the militant arm of the Adeptus Ministorum. Pure of heart and fanatical of devotion, they place the worship of the Emperor above all other concerns. They maintain holy places anywhere where His subjects might be served, tending to the needs of the poor and the sick as well as spreading the word of His glory to all that might listen. But not all are worthy, and for those that aren’t - only merciful death can be granted.

Gameplay Mechanics

• Shield of Faith: Units have an Invulnerable Damage Reduction against all damage and a Witchfire Damage Reduction.
  
• Acts of Faith: If they have enough morale, units can perform Acts of Faith abilities to get temporary bonuses.
  
• Holy Trinity of Weapons: The main weapons of the Adepta Sororitas are the Bolter, the Flamer and the Melta.
  
• Sacred Rites: Pay influence to provide one short Faction-wide bonus to the Adepta Sororitas. Can be upgraded to two Sacred Rites at once.
  
• Martyr Spirit: When a unit dies, adjacent units benefit from a 17% morale loss reduction for 1 turn.
  
• Convent of Faith: Each tile in a city confers +1 Loyalty.
  
• Requisitions: Food and ore resources are replaced by a single soil-independent requisitions resource.
  
• Sororitas Holy Site: Exploring a Sororitas Holy Site with Hospitallers gives a research reward. The quantity of Holy Sites scales with the map size. The research reward scales with the number of turns.
  
• Oath of Faith: Broken units cannot use their Shield of Faith and Deal 50% less damage instead of 33%.
  
• Religious Enclave: All the cities of the Adepta Sororitas built after their first are limited to a one-tile radius and cannot develop further.
