(E) Illic Nightspear, The Walker of the Hidden Path

Shots fired by models with this special rule (excluding Snap Shots) are always Precision Shots as described in the Precision Shot special rule (see Warhammer 40,000: The Rules).

If Illic Nightspear joins a unit of Rangers, all Rangers in that unit gain the Sharpshot special rule whilst he is a part of that unit.

If Illic Nightspear deploys using the Infiltrate special rule, he can be deployed anywhere on the battlefield that is outside of impassable terrain, regardless of enemy proximity.  If he begins the game with a unit of Rangers, all Rangers in that unit benefit from this rule.

Whenever a unit is completely destroyed within 7" of one or more non-vehicle units that consist only of models with this special rule, pick one of those units to make a Soulburst action.  You cannot pick a unit that is locked in combat, Falling Back, or that has Gone to Ground.  A unit making a Soulburst action can do one of the following, even if it has already done so in this turn:

* The unit can immediately move as if it were your Movement phase.
* The unit can immediately shoot (or Run or Turbo-boost) as if it were your Shooting Phase.
* The unit can immediately make a charge move as if it were your Charge sub-phase (if they do so, enemy units can fire Overwatch as if it were your Charge sub-phase). A unit that makes a charge in the Fight sub-phase does so at the end of the current Initiative step, and once they have charged, the Initiative steps continue to resolve as before (including for models in the charging unit).

A unit can only make a Soulburst action once per turn.

A unit composed entirely of models with this special rule can re-roll one or more of the dice when determining Run moves and charge ranges (such as a single D6 from a charge range roll, for example).

This rule is often presented as Hatred (X) where X identifies a specific type of foe. If the special rule does not specify a type of foe, then the unit has Hatred against everyone. This can refer to a Faction, or a specific unit. For example, Hatred (Orks) means any model with the Ork Faction, whilst Hatred (Big Meks) means only Big Meks. A model striking a hated foe in close combat re-rolls all failed To Hit rolls during the first round of each close combat.

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.

Units that contain at least one model with this special rule are deployed last, after all other units (friend and foe) have been deployed. If both sides have Infiltrators, the players roll-off and the winner decides who goes first, then alternate deploying these units.

Infiltrators can be set up anywhere on the table that is more than 12" from any enemy unit, as long as no deployed enemy unit can draw line of sight to them. This includes in a building, as long as the building is more than 12" from any enemy unit. Alternatively, they can be set up anywhere on the table more than 18" from any enemy unit, even in plain sight.

If a unit with Infiltrate deploys inside a Dedicated Transport, they may Infiltrate along with their Transport. 

A unit that deploys using these rules cannot charge in their first turn. Having Infiltrate also confers the Outflank special rule to units of Infiltrators that are kept as Reserves.

If a unit has both the Infiltrate and Scout special rule, that unit can deploy as per the Infiltrate special rule and then redeploy as per the Scout special rule.

A unit that contains at least one model with this special rule rolls an extra D6 when rolling to move through difficult terrain and is not slowed by charging through difficult terrain. In most circumstances, this will mean that, when moving, the unit rolls 3D6 and picks the highest roll. Furthermore, a model with the Move Through Cover special rule automatically passes Dangerous Terrain tests.

A unit that contains at least one model with this special rule counts its cover save as being 2 points better than normal. Note that this means a model with the Shrouded special rule always has a cover save of at least 5+, even if it's in the open.

Cover save bonuses from the Shrouded and Stealth special rules are cumulative (to a maximum of a 2+ cover save).

This rule is often presented as Preferred Enemy (X) where X identifies a specific type of foe. If the special rule does not specify a type of foe, then everyone is a Preferred Enemy of the unit. A unit that contains at least one model with this special rule re-rolls failed To Hit and To Wound rolls of 1 if attacking its Preferred Enemy. This applies both to shooting and close combat attacks.

If a model with this special rule rolls a 6 To Hit with a shooting weapon, that shot is a 'Precision Shot'.

Wounds from Precision Shots are allocated against a model (or models) of your choice in the target unit, as long as it is in range and line of sight of the firer, rather than following the normal rules for Wound allocation. A character that has a Precision Shot Wound allocated to it can still make a Look Out, Sir roll.

Note that Snap Shots and shots from weapons that scatter, or do not roll To Hit, can never be Precision Shots.
