Acolyte Iconward

Friendly units with the Genestealer Cults Faction within 12" of this model have the Feel No Pain (6+) special rule. Models that already have the Feel No Pain (excluding Acolyte Iconwards) special rule instead add 1 to their Feel No Pain rolls.

Units with this special rule that Infiltrate, or that arrive from Reserve or Ongoing Reserve, can chose to roll on the Cult Ambush table instead of deploying or arriving from Reserves normally. Unless otherwise specified, ambushing units move onto the table as described for other Reserves and cannot move any further during the movement phase. Units cannot use the cult ambush special rule whilst they are embarked inside a vehicle.

A model with this special rule automatically passes Look Out, Sir attempts, and can even make Look Out, Sir attempts when fighting in a challenge.

Instead of moving in the movement phase, any unit with this special rule that is not within 6" of any enemy models, can be removed from the battlefield and placed into Ongoing Reserve. A unit cannot Return to the Shadows in the same turn it arrives from Reserves or Ongoing Reserves, and cannot do so whilst embarked in a vehicle.

Independent characters can join other units.  They cannot, however, join units that contain vehicles or Monstrous Creatures.  They can join other Independent Characters, though, to form a powerful multi-character unit!  Independent Characters pass Look Out, Sir rolls on a 2+. A unit that contains one or more Independent Characters does not need a double 1 to Regroup if reduced to below 25% of its starting numbres, but instead tests as if it had at least 25% remaining.

Full details in BRB. Rule too long to copy verbatim.

When a model with this special rule suffers an unsaved Wound, it can make a special Feel No Pain roll to avoid being wounded (this is not a saving throw and so can be used against attacks that state that 'no saves of any kind are allowed', for example those inflicted by Perils of the Warp).

Feel No Pain saves may not be taken against Destroyer attacks or against unsaved Wounds that have the Instant Death special rule.

Roll a D6 each time an unsaved Wound is suffered. On a 4 or less, you must take the Wound as normal. On a 5+, the unsaved  Wound is discounted - treat it as having been saved.

If a unit has the Feel No Pain special rule with a number in brackets afterwards -Feel No Pain (6+), for example - then the number in brackets is the D6 result needed to discount the Wound.
