The most skilled fighters of an Order will be collected together into specialised squads. Cetestians are ferocious fighters whose burning hatred of the Emperor's enemies makes them virtually unbreakable in combat.

Squad: The squad consists of one Sister Superior and between 4 and 9 Celestians.

Weapons: Boltguns. The Sister Superior may exchange her boltgun for a bolt pistol and a close combat weapon at no extra points cost.

Options: Up to one Celestian may be armed with one of the following weapons: a heavy bolter at +10 pts; a heavy flamer at +15 pts; a multi-melta at +25 pts.

One Celestian may be armed with a flamer at +3 pts, or a meltagun at +10 pts.

The squad may be equipped with frag grenades at an additional cost of +1 pt per model, and krak grenades at an additional cost of +2 pts per model.

Characters: The Sister Superior may be upgraded to a Veteran Sister Superior for an additional cost of +10 pts.

Rhino: The squad may be mounted in a Rhino armoured carrier at an additional +40 pts.

Holy Hatred: Celestians are fervent adherents to the Imperial Creed, able to summon up a righteous hatred of any foe they are facing. Celestians gain +1 Attack in the first round of close combat, regardless of whether they charged or not (note that if they did actually charge there is no additional benefit).
