The blessings granted by Shallya fall into two main groups: those that allow her servants to heal the troubles of the world, and those that allows them to endure those troubles to bring relief to the suffering.

Blessings of ShallyaURL Copied!
Priestesses of Shallya know the three Prayers listed below. Prayers are innate bound spells (power level 3). All Prayers are augment spells. In addition, the Priestess may channel Power and Dispel dice just like a Level 1 Wizard.
Shallya's Endurance: The Priestess invokes the power of Shallya to temporarily boost a target's vitality. When cast, the unit she is with (but not herself) gets +1 to its Toughness until the start of her next Magic Phase.
Compassionate Mind: The Priestess reassuring prayers resolve her fellows' minds to face the horrors of the world. When cast, the unit she is within gains the Immunity (Psychology) and Stubborn special rules until the start of her next Magic Phase.
Purify: All hex spells effecting friendly units within 12" are automatically dispelled. In addition, any units with the Daemonic, Vampiric or Undead special rules in base contact with the Priestess or the unit she is with suffer D6 Strength 5 hits.
