Warlock

A unit containing 1-3 Warlocks or Warlock Skyrunners is Mastery Level 1; a unit containing 4-6 is Mastery Level 2; a unit containing 7 or more is Mastery Level 3.  If a unit's Mastery level is reduced as the result of models being removed as casualties, select one psychic power known to the unit for each Mastery Level lost.  That power is immediately lost, and cannot be used for the rest of the battle.  This unit generates one Warp Charge point at the beginning of each Psychic phase for each Warlock or Warlock Skyrunner in the unit, regardless of its current Mastery Level.

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).

A unit containing at least one model with this special rule is a Psyker unit - if no Mastery Level is shown, then that unit has a Mastery Level of 1. Rules for generating and manifesting psychic powers can be found in the Psychic phase section. The unit follows all the normal rules for Psykers, with the following clarifications:

When manifesting a psychic power, this unit measures range and line of sight from, and uses the characteristics profile (if required) of, any one model in the unit that has the Brotherhood of Psykers/Sorcerers special rule (controlling player's choice).

If this unit suffers Perils of the Warp, or is hit by an attack that specifically targets Psykers, the hits are Randomly Allocated amongst models with the Brotherhood of Psykers/Sorcerers special rule. If a model with this special rule gains or loses a psychic power, all other models with this special rule in their unit also gain or lose that power.
